When I am driving my car and put my foot on the clutch to shift or sit, it starts to rev up to about 2000 and back down. If I stop and let it sit a little while the idle eventually gets back to normal, but when I start driving again, it strats up again when I am in neutral or when my foot is on the clutch. Any ideas? I have a 95 tsi awd. Only mods are full 3" Apexi N1 exhaust, boost guage and K&N filter.
thanks

Do you have a check engine light at all?

He doesn't have a CEL. I replaced the BISS oring for him today and he hasn't noticed the surge yet. The old one was quite hard. I don't know why he posted this...

Still have the problem. Any more ideas? I replaced the o ring on the biss and cleaned out the throttle body and they didn't fix the problem. Tonight coming from work, it was killing when I put my foot on the clutch. I am thinking it is the same problem. Sometimes it is fine, sometimes it will go up and down from 1500-2000 and sometimes it will go from 1000-1500.
Thanks James

Do you have a vented BOV or is it still blowing back into the intake?

Have you checked the ISC? I would test that first.

Just to help out james with his car. He did have a stock 2g BOV on when it was happening. He tried to fuck around with it and broke the nipple off. He is know using my old Turboxs RFL type H. So yes he is venting. It is still happening though I think....

How do you check the isc? It has nothing to do with the bov. Sometimes when it is steady, it just sits too low and kills. Sometimes it idles at around 200-300 rpm and just drops a little.

BTW-John broke the bov, not me. We will be able to fix it as good as before though with JB Weld. That is what was holding it on before. ;)
