:16: :P :P :P

anyway my problem is when i reverse out of the driveway and i am starting to go up a slight hill i press the throttle and nothing pedal straight to the floor and stalls

 

 

did it help with the stalling problem??

[smoggy7]

hi guys ok yes it did stop the stalling but.......... we now have a small problem in the low gears 1 & 2 going slowly across a flat road or in a line of traffic going slow it is jumping - jerking slightly we took the maf back off to check the rubber seal all ok but where it flatens out you can see the rubber we think there may be air escaping from this or should it be like this? will i have to have it reset or something ? it wasnt doing it when the old maf was on it so what can this be any ideas guys thanks smoggy7

 

 

i have included a pic where the flat bit on the maf is there is a gap here and we think the air is coming from there we are not sure if you put your finger there and rev the engine you can feel it sucking on your finger can someone suggest what the problem may be again thanks alot for your patience with me smoggy7

What's a M.a.f? have I got one - do I need it fixed?? :D

 

Sounds good. Does it fix climate control problems :D (only kidding about cc - only a lot of cash fixes that!!)

A leak at the air-filter end should not affect the engine. Perhaps you also have another fault like a temperature sensor problem.

How much did the MAF cost, did you fit it yourself ? Theres one here on good old ebay:

Smoggy,

 

Why not try popping the old one back - or just try leaving the plug off. It won't fix anything but it may help to make sense of things. Golden rule of fault finding - 'If it doesn't make sense, one step back and look again.'

 

TinTent Tourist,

Of course you've got one! It tells your engine management thingy how much your engine is sucking in so that it can administer the correct amount of fuel and all sorts of other clever stuff.

 

They can cure and cause all sorts of problems including some totally rediculous auto gearbox behaviour. I've had reports of insomnia and washing up hands but thats probably a bit extreme.

 

Look, listen, learn and worry. Then go for the pills cos, short of replacing the blooming thing, there seems to be no sure fire way of proving that it's faulty.

 

jkspoff,

 

I've just bought one for about

[smoggy7]

hi, the maff was

[NikpV]

Could you put some duct tape across the gap - if nothing else it would reassure you that it is not causing a problem, from your photo it appears to be upstream of the maf (air filter side) so it shouldn't (as MM said) cause any problems for the ecu metering th fuel. In the long run it does mean unfiltered air hitting the maf - I wonder if that would shorten its life???

[smoggy7]

hi guys, ok i took the plug to the maf off and altho it lacked the power i didnt get the jump/ hesitation, i drove slowly for a little while and nothing , so then i reconnected it and there was a slight hesitation noticeable, so where to i go from here? i was thinking could it be a blocked injector? or a bad batch of diesel will wait a few days and see if it makes any changes thanks for the input you guys but its startting to get on my nerves a little now a brand new maf and it starts to play up where as the old maf was not making the car jump/ hesitate so any ideas guys will be helpful here later smoggy

I'm no expert but a couple of things....

 

 

Are you sure it's the correct MAF? It can be removed easily from the side of the housing if you have the correct torx screwdiver. I've been trying different mafs in mine and leaving it running without replacing the screws and no problems.

 

Did the mechanic change the insert or the whole thing. If he changed the whole thing, he may have disturbed the push fit pipe that comes out of the aire filter box at the top rear. You have to lift the cover off (as if you're changing the filter) to check this.

[smoggy7]

hi, the maf is the correct one has the same part number on it pbt-gf30 bosch we have also checked for loose connections etc all ok, so next i thinkis the injector cleaner just to make sure its not those, then we will take it from there smoggy

[smoggy7]

hi,you were saying about the push fit pipe at the rear of the air filter box my airfilter box hasnt got oone? i have looked and i cant see it, unless its further down at the rear of the box but cant see any pipes coming from it thanks smoggy

[Scorpiorefugee]

Mine's an S reg, not sure what power rating, but it has one but I've no idea what it does, although I do remember panicing when I forgot to put it back. It is at the top rear of the air filter top cover and pulls off very easily if the box is disturbed. From what you've already said about your problem this is probably nothing to do with it and yours may not even have one so lets hope someone else can suggest something,

[smoggy7]

hi thanks for the input, i have looked again today and mine isnt at the top so i guess i dont have one however i do have under the air filter an opening in the shape of an oblong so i guess my air goes out that way but i cant see the pull off pipe at the top rear of it maybe different, also i was told today that if my car wasnt jumping/jerking before with the old maf then it must be a duff new maf so i phoned the guys where i got it from and are willing to change it tomorrow morning so will try that if not i honestly dont know what the hell to do apart from taking it to be put on a machine last resort trouble with these new cars all electronics pain in the arse (sorry for the lang) but a little pi**ed off now spent a fortune on her in the last few months with one thing and another had this one for 14 months so hope i can get this sorted i though someone on here has had this problem not only with the new fitted maf but the serging or jerk or jump whichever you want to put it but we will get it done in the end thanks alot smoggy
