hi guys (and girls ) can some one help me out? i got a 1.8t A3, when i accelerate in any gear there seems to be a pause of a second or so before the power is put down! the engine idle also changes between 850 and 950 revs! what could be causing this?? i've taken the MAF sensor out and cleaned it (in petrol ) but that hasn't worked! hope some one can help cheers in advance
when the engine is idling, if i give it some gas then let off the revs drop to 500 then rise to 1000 before returning to 850-950, this can't be normal can it??
Do the revs drop like that when the engine has just been started or when it's fully up to temp? I think either way it might be a duff sensor of some sort or maybe a leak? Have a look for fault codes if you can. What age is the car? If it a 2000 onwards then the 'lag' that you might be feeling could well be the short lack of response from the Fly-By-Wire controls.
no it a 1997. if i disconnect the MAF sensor, the idle becomes constant at 900 revs. so yeah, a duf sensor would be right! cheers for that. now all i have to do is get the 70 needed to buy a new one [:^(]
