Gently touching the gas pedal = stalling?

[Jonas_R]

Well,

If i just touch the gas pedal very gently it makes the car stall, or the idle drops from 900 rpms and down to 400 rpms. It then gets back up again to 900 rpm. I thnik this is very strange, cuz the idle is very smooth when it is at 900 rpm, is is not going up and down.

Well it is not the ISV, MAF, TPS, N75 all brand new.

So is there any other sugestions to what might cause this problem? I mean I dont have a clue to what the hell is causing this? Could it be a bad O2 probe og perhaps the plugs are bad? Well any suggestions would be helpful

Fuel Filter??

[Jonas_R]

Was also my first idea, but that is also new and so is the fuel pump.

It seems electrical in my opinion

I would say TPS, no fuel enrichment with throttle opening or ignition timing way out would cause it to stall. Seems you have covered those areas though, very odd

[Jonas_R]

Yes it is indeed very odd
But will try new plugs, O2 probe and clean MAF, ISV, and all the different connections on the sensors and see if it helps.

Have you re-set your new TPS?

[Jonas_R]

No, how do I do that? It is a 1992 s2 Coupe 3b?
