2002 2.3 Petrol Gal Running Problems When Up To Temp

[Paulchez-85]

Hi all. I have a problem that I hope somebody can help with. The car will run ok when It 1st starts up but after maybe 10 minutes of driving and the car gets up to running temperature it seems to lose all power. The car will bog down if I try to give it anymore throttle than what's needed to keep it running. I have put the obd2 scanner on it but not getting any tech's. I have taken the maf sensor off and cleaned it with carb cleaner although it looked clean. I have changed the coolant temp sensor as I was not getting a reading from this. I will be checking the 02 sensors as soon as I can when it stops raining. I've checked for vacuum pipe leaks at the throttle body area, intake leaks and I'm coming up short.I have also just had to renew the common fuse box fault in the engine bay with the frazzled wire (2nd down, main fuse box supply if I'm right). Changed the alternator wire also but joined the other cable approx 18" back so good cable and was joined by overlapping the 2 cables and crimped using a hydraulic crimper so a good solid super tight join has been made and covered with heat shrink then taped back into loom. Could this be related? Any help would be greatly appreciated as this is the only family car and need it for the school runs in a couple of days. Thanks in advance.

Can you see any actual sensor data with the obd scanner you have got? If not try unplugging the maf and driving the car like that - it should revert to a default map having done so, if this improves it then your maf is probabbly dead.

 

The other thing to look at is the o2 sensor reading if you can get visibility of the sensor value - it should flick around between 0 and 1v, if its stuck at one reading or reading nothing then its either the sensor or wiring at fault.

 

Doubtful the wiring you've fixed is the cause unless it happened immediately after fixing the wires?

[sparky Paul]

Is it misfiring or just holding back? Coil failure is common on these, often failing when engine hot. Throttle will show up a weak spark too.

 

What's the condition of the plugs? They must be changed at scheduled interval, they are totally kaput after 40,000-ish miles.

hi brianHh and thanks for the replies. no I cant see live data with it but is not showing any codes, ive unplugged sensors and done another scan and its brought a fault up with the code for the sensor unplugged. have tried the maf sensor and didn't make a blind bit of difference. have tested both 02 sensors and both give a reading of .956v when heated and drop back to 0 fast. have tested the heating circuit resistances and again giging perfectly good results being 10.5 with multimeter on 200 ohm. also cat was shot another ordered. also im not getting a cel light/ engine management light when key is turned to position 2. don't know if its all related, etc. a ecu fault?

thanks again. 

[Paulchez-85]

hi sparky paul and thanks for the reply. I would of said neither. it seems as its either over fuelling and under fueling massively. when accelerator is pressed it just bogs right down losing power and speed. spark plugs were replaced around 6 month ago when I bought the car and have done maybe 2k on them. wouldn't a faulty ignition module give constant spark problems including starting probs. please forgive me questioning your question but really just trying to get to the bottom of it as this is really stressful. aswell as causing sleepless nights after 3 weeks of agro its now going to be cosing me £200+ a week in school runs until sorted. gggrrrrrrrrrr. also the plugs were new when I bought the car maybe 6 month ago with around 2k done on them.

 

thanks again

Doubtful the ecu is faulty - can you monitor the pre cat o2 sensor output with the engine running (it should flick about - I've had one fail and not throw up an error code despite being stuck at 0.35v).

 

And no a faulty coil pack may have only partially failed - they usually start playing up when under load. Given further use your likely to find it gets worse though. Do you have the coil packs on the top of the rocker cover on yours? I've had engines run (badly) and start with a failed coil pack where only 2 cylinders are working (the other half or other pack was still working ok though)

 

The cat won't be the reason for failure - you need to fix that before you fit it.

[Paulchez-85]

hi brianh. thanks again for your reply. not really sure about monitoring the 02 sensor I can give it a go when I get the cat on. I have the 4 leads and ignition module not the 2 leads & 2 coil packs. I think im going to get the inline ignition testers and plug them in between the module and leads. so you would advise sorting the car before putting the new cat on? I was only thinking of the ecu as im not getting a engine management light when sensors are pulled or when ignition is turned to position 2 either. I just remembered that my £10 fleabay diagnostic scanner DID bring up a fault but showed as N/A. as these only bring up generic codes im not sure what it could be.

 

all your help is really helpful and appreciate all of it and hopefully I can sort it with all the help.

[BrianH]

Yes on sorting the car before mounting the cat - the car will destroy the cat if you don't resolve the problem first.

 

If you can find a suitable bluetooth obd module and have an android phone the torque app will allow you to monitor the o2 sensor directly as well as maf etc - Otherwise you need to get a multimeter onto the signal wire and see what its doing.

 

The bluetooth module will need to support the right protocol - SAE J1850 PWM (41.6 kbaud) I think is the right one - few people have had issues finding an adaptor that actually works with this (me included - i've got one of the hhobd ones that does work, and another that does not despite them being nearly identical).

 

It might be worth running it into one of the independent motor factors and seeing if they can have a look what they think might be the cause - No guarantee they will be able to help, but if you don't ask you won't know!

[Paulchez-85]

hi brianh. thanks, ive got it into my mates garage hopefully tomorrow to go on his diagnostics and hopefully been a garage will pull every problem the car has to show. ill update what is found and any probs that it shows and hopefully my problems now may help people in the future. I cant believe this mk2 as I never had this amount of problems with my S reg galaxy which is why we came back to them from the discovery . I was going to get a mk3 but it seems the newer the galaxy's get the more problems they have.. ill update once I have the diagnostic results.

 

cheers

[BrianH]

Sounds like the best plan you've got there - get someone to take a look with the tools for the job to have a look at it. If the sensors look ok i'd be looking to either swap the coil pack or the plugs (even new ones occasionally go wrong!)

[Paulchez-85]

cheers. hopefully I can get pin pointed problems and ill be sure to let the forum know whats been found, have a check in the next couple of days to see what ive come across.

 

thanks

Hello and just a quick update on the problems. Turned out to be the cat blocking the pipe. Garage nicely butchered the cat and ripping out the innards and welded it back up after being asked not to do anything other than do a diagnostic test. Then had the courtesy to charge me £160. This is why I don't do garages total rip off merchants and I still need to replace it with a new cat. Why not just put a new cat on and have done rather than spending the hours messing about other than for more money. Never again.

[gregers]

then why pay it if you had already told them not to do any work.

i certainly wouldve argued about it.

i bet it wont pass an mot now.

[Paulchez-85]

Hi preggers. I clearly told them only to do a diagnostic check nothing more and told them I already had the part to go on. As I wanted my car back I had no choice but to pay. The only upside is I now know what was wrong and had bought the right part BUT I was told there was no fault codes so I'm still unsure why it broke down like it did. Could have the same problem in a few month if something was missed and causes the same prob. The only difference been I will know what it is and will store it in the memory bank for future reference. New cat going on when I receive the new 02 sensors and have bought a program so I can monitor it myself. Still have no engine check light at all so maybe have to check bulb then ecu?

[BrianH]

If its not logging any fault codes it won't bring the light on - If someone else with a petrol mk2 can confirm the light may come on when you turn ignition on but don't start the engine straight away - if so this should allow you to try the same on yours to confirm.

 

Otherwise disconnect something (MAF is a good bet as its easy to get to) and that should log a code and bring the light on. You may want to have a means of clearing codes beforehand though.

 

Only thing i can think has caused the failure in the way you describe is if part of the ceramic had broken off the cat and become lodged in the exit pipe from the cat - I've only known that to happen once to me, and that was the result of the car misfiring due to a combination of problems, the main one being a o2 sensor that wasn't reading correctly.

[gregers]

i know ive put on a bit of weight,but preggers nah defo not.

if i am then its a miraculous conception.

[Paulchez-85]

Hi gregers. I can only apologize and explain it's the predicted text on the tablet. My sincere apologies

[gregers]

paul no probs m8ty,if i was that bovered i wouldve edited or deleted it.lol

 

banter,were missing that here.

[Paulchez-85]

ok mate nice 1

[sparky Paul]

Made me chuckle :)

i do resemble that post to be honest,

glad it made you smile.

Hi guys - sorry to hijack the thread but thought it better than starting yet another one! Just wanted to clarify whither the 2.3 duratec engines in the Galaxys have an electronic/fly by wire throttle body or wither it is a cable job? Many thanks in advance 

Mark 

[sparky Paul]

This is in the mk.1/2 (1995-2006) section of the forum, and the 2.3 engine from these cars has a cable throttle - but it's NOT a Duratec engine.

 

The later mk.3 cars are Duratec, no idea what the throttle arrangements on those are. You might have better luck asking in the mk.3 section.

hello brian h and sparky paul. im still having trouble with my motor just had it into an auto electrics and have been told the 2 data wires ( og/bn + og/bk I think he said) is the cause of lack of communications with everything on the car. ecu, central locking module, airbag module and so on. im just wondering if anybody knows of any places these break or can list everywhere they go to.

 

cheers and thanks in advance
