low RPM surging in 97 GTS???

[jason427]

I know with my 94 I adjusted the throttle bodies but the newer ones are different.
Is there any other reasons a 97 GTS would surge at low rpm's (1400-1500) or is this normal for Gen II's ???

Thanks,
Jason

not normal. Have you checked your plugs / wires? Have an ODBII sensor? Getting any error codes?

I did look at the plug wires and they are all attached. That is the first thing I looked at. I did run a 12.30 @ 118.5 in FL heat so I am assuming there is nothing major wrong.
I will run a scan and see if anything pops up. I have not seen any check engine lights or anything.

Any other info/tips would be great...

Thanks,
Jason

Driver side Throttle position sensor. Perhaps not making good contact? simply unscrew, unplug, clean and reattach. IAC motor? Be careful when unbolting (located passenger side, near front valve cover) so as to not damage gasket. Again, clean (you can spray cleaner in it) and see if that helps any. Just some simple thoughts that have helped me in the past. But most likely it sounds like throttle bodies slightly out of synch.
