idle problem with revs

[daltah]

When ever I try to hold my rpms at 2k or 2.5k it will bounce up and down it will not stay there. It either want to keep going up or will bounce up and down. Is this a sensor or what?It only does it in neutral or when the clutch is in. I have a 95tsi awd.

Can someone help me out. I need to know asap to pass emessions.

You might want to do some research on idle surge. Sounds like you have a case of it.

When I idle its fine. It only does it when I rev the engine and try to keep it at a certain rpm.

Still your getting a surge. Search Idle Surge and you will find what you need. There are like 10 different things that cause that. Dirty throttlebody, to tight of throttle cable, bad ics, bad tps, ect. Just search.

The ECU won't surge if the Idle Position Switch is open like it should be whenever your touching the throttle. Since you have a 2G that would imply that your TPS is misadjusted. Have you touched it?
