Default somebody help me!

IAC count is 0 at idle, TPS voltage 0.57, Idles fine. When rolling RPM sit a little high as long as the clutch is pushed in. If i take it out of gear while moving and let out on the clutch it starts revving, like 3500 rpm's. I've checked all the vacuum lines i can find and hosed every line down with WD40 and found nothing. HELP!!!

hi,

please give us more detail on the vehicle.
check the throttle blade to see if it is sealing up properly and also check to see if there are any holes on the blade. also check the idle airflow values, and the tps threshold

hope this helps,

volkan

car is stock. i put a new o ring on the IAC today and it seems to be running better, but my IAC count is acting weird. When i first crank it, it starts around 96 and slowly drops to 0

+1.

You should not have an IAC count of zero unless the throttle set screw is holding the TB blade open or the hole in the TB Blade has been opened up too much.

Use brake clean or carb cleaner. WD40 is oil.

The AC vacuum line and brake booster vacuum lines are in the back. Also, the AC line is attached to a T which I have seen many break. That line is sometimes in the loom and is plastic, not rubber.

This is my exact problem. And this morning my traction control module started ticking with the key just turned to accessories (which in turn kind of ratcheted my throttle cable back and forth a tad)

For the OP, were you able to isolate a leak or fix the problem? I've heard of all the possible problems with these car symptoms, but not a single resolution/fix.
