Audi S2 TPS problems...

Disregard that, I misread.

You probably have a boost/vacuum leak, pressurize the intake.

[Carfreak]

Nope.. the only thing is small, small missfires at idle, 2-3secs intervalls..

the sparks look all great... the afr is at 14,7 at idle, around 11 at full boost (1,7bar) with 630cc inj.

Theese symtoms just happens at crusing without any boost or anything, att WOT nothing strange happens at all.

[prj]

Do you get loud bangs out of the exhaust when this happens?

[Carfreak]

awesome!


Stil havin major problems with the car at low speed and cruising.. It stumbles and when I press down the clutch the rpm drops and bounces upp and then down and the engine dies :/

I have no leaks what so ever, pressurised it to 2bar..

Is there any way of diagnose the MAF in vag-com ??

[prj]

Yes, this is OK.

It is also not percentage, but degrees.

[Carfreak]

Just wounder..
Looked in Vag-com and with the engine at idle I have 7,9% TB angle, is this right ? Shouldnt it be at 0% at idle and with the engine off ??
At WOT I have 99,9% TB Angle..

I don't understand why there would be confusion but...this might help you (written for the AAN but should have some info that applies to your engine):
