audi s3 powerplaying up in 4th, 5th, 6th gear?
Hi can anyone help
I have and Audi S3 2000 model and in 4th, 5th an 6th gear there is no power the boost is up and down on the boost gauge until you get just over 5 thousand revs and then it goes like **** off a shovel. It is fine in 1st, 2nd and 3rd gear.
i have tried the following
I have tried taking the small air pipe of the achuator and the boost will hold problem seems much better but still not quite wright. the power still seems to kick in just over five thousand revs but it is alot better without it on.
- air flow meter
- n75 valve
- new coil packs
- new spark plugs
- fuel filter
- took the car to a rolling road to get it mapped but it does not show the computer but he can see the problem but doesn't know whats wrong with it.
- cleaned all oil breathers and injectors
please help it is doing my head in now!!!
