Hey all

My 1.8T AEB quattro manual is suffering from some kind of power problem.
The car has done 140 000kms and is a 1997 model.

I have the APR ECU modification and a single mass clutch which I put in about 5 months ago.
Under hard acceleration I find that the car splutters slightly. It does not jerk around, but I can feel that there is a struggle for power.
I have replaced the oil, plugs, fuel filter and the timing belt was done around 10 000kms ago.

Does anybody have any ideas/suggestions. The only thing I can think is ther gap in the spark plugs (.028" is reccomended for chipped cars over the standard .032").

Any help would be appreciated

 

have it scanned

vac leak. MAF problem.

my two best guesses

 

Hi

I have not considered that as a possibility. Why would that be causing problems, I like to know how things work is all.

Thanks

 

MAF, any other symptoms like check engine light flashing? maybe coilpacks?

 

Hi

I have never had any dash lights come on while driving. Coilpacks are fairly expensive so i'd wanna know for sure if it is the coilpacks that were causing the issue.
Could the spark plug gap fix such an issue?
And could an MAF cause the problems but not throw a CEL?

Thaks

 

If the plugs are gapped wider than .028" then they can cause it. Scan the car - latent codes may exist and point you in the right direction.

 

Hey all

Thanks for your replies

I just purchased a new MAF and thermostat from ECS tuning. Will install and let you know how it goes. I will also be gapping my spark plugs to .028.
