Chugging /jump/miss?

[smoggy7]

hi guys , ok have had all the checks done as far as we can go with this now, we changed the fuel filter today full of water so we thought ok thats it cracked it so went for a spin after fitted and guess what still the blood same, have i got to wait now until the water whats left of it goes through the system? or do it need now to go in on the machine? also i have bben told how far this is correct i do not know but a while back i had my timing belt change with the maf not working now i have had this changed would it be the timing has changed in some way and needs the machine to tweak it a little due to it being electronic thanks for all the input on this many thanks smoggy

 

the only way to describe it is if you change to a higher gear to soon thats the kind of chugg/jump or miss that i am experiencing it will go 0-70 now no trouble since the maf was changed so happy with that at least.

hi guys, ok just had which i think maybe the right answer i am looking for the timing, can you tell me how do i go about getting this set ? do it have to go on the machine for this? also i had the timing belt changed when the old maf was duff would they have put the timing right to the maf or doesnt this have anything to do with putting on the new maf thanks smoggy any idea of cost to get this done?

Timing is not affected when you change the MAF sensor. The timing should have be set when the belt was changed - its mechanically set and should be correct if they followed the correct procedure. No timing "tweak" is possible and if it was tooth out - you'd know about it - the engine would run like a pig if at all.

 

Water is a definite possibility - maybe you have half a tank full - try emptying the fuel filter again, checking for water.

hello seatkid , well this is only happened since i put the new maf on if i put the old maf back on it doesnt chugg or nothing just the loss of power up hills sluggish like, strange one this

 

if you are in a line of traffic going slow then you can feel the hesitation then up to 2nd still feel it then as you go into 3rd it chuggs quite ruff you can actually hear it if the windows are down chugg ,chugg,if i put my foot down from the off 1st, 2nd,3rd,4th it dont happen, i think i got a lot of people stumped on this one but happy for some ideas as its doing my head in, i will try and discoonect the new maf tomorrow and see what it does and let you know thanks mate smoggy7

Dont know if this is true or not,,,,,,,but on an american site it said your need to disconnect the battery for 30 mins,, which wipes the ECU and when you reconnect the battery go for a drive and it learns a new maff has been fitted,,,,apperantly you are suppose to do this for all new sensors fitted that talk to the ecu!!!!!!!!!!!!!!!!!!

 

 

Has I say dont know if this is true or not ,,,, has I cant find the site to link to :D

hi guys ok i have tried that still no joy, so today i disconnected the maf and it didnt chugg or jump once what the hell is going on here, it drove ok without it connected , but soon as i re-connect the maf the chugging starts so i think it has to be the maf im sure of it why dont it chugg without it but as soon as i connect it it chuggs? also can someone clearafy the rubber that is on the maf as i was thinking maybe my mate has put it in the wrong place ok on the end where the rubber goes does it go at the top or on mine i have a ridge and it is sitting there , i just thought that maybe this is stopping the right amount of air into the system i did have a look at some pics of the maf that someone has kindly left but mine is slightly different his rubber was sitting at the top i tried sitting mine in the same place but will not close tight together or is it supposed to be any ideas here plz thanks smoggy7

hi all, ok my wifes cousin has just done a test on his computer dianositic no fault codes were found apart from the temp gauge was reading 90 degrees but his machine was reading 170 , i have just found out that 90cel degrees is 194 f so would this affect the running of the car , i am now in the house as my father in law wanted to use the car so when it returns i am going back down the garage for further testing but can anyone suggest anything as the jump is still there on my way back home i tried to get it to do it with him in the car but couldnt get it to do it as usual lol thanks smoggy7

hi again well a big thank you to mask he was spot on the temp sensor is faulty it is reading 90 degrees celcius on the dash board and his machine is only reading 170 f / this should be reading after the calculations 194 degrees cel so looks like the fault , i took it to my wifes cousin who we didnt know up until today has the dianostic tool as i think my other mate must have looked at the wrong switch lol but anyway thanks mask hopefully this is the cure and fingers crossed its the cause of this jump/chug or whatever you want to call it anyway thanks to all of you for your input once again many thanks

 

he also bridged the wire to the other sensor on the rad and the fas are also kicking in so they work ok as they dont kick in at all as the temp gauge dont go over the 90 when stuck in heavy traffic so the fan wont kick in at all
