I'd look for a vacuum leak, possibly the large hose that goes to the brake booster-use a can of throttle body cleaner and spray around hose areas while engine is running and listen of drops in idle-there's your leak.

When I crank my car my idol goes above 2 and then falls down below 1 and then it does a couple of times and then it dies sometimes. when I'm driving & stop and then go it sputter & idol does again


Try changing the tpi throttle positioning sensor found on the throttle body . Check air filter, clean air mass flow sensor.located sometimes in air box ,or after going in throttle body black hose, going in air box usually found in those two spots. If no change. Then I would check o2sensor start whith the cheapest first.
air box / hose going to motor look for a set of wires
unplug wires and pull out clean or replace. Spray whith brake cleaner starter fluid or similar.
Tpi throttle posistioning sensor.
last but least
o2sensor sensor.

Have you checked for vacuum leaks ?

Spray a small amount of starting fluid around all suspected areas and if it revs up that's where you leak is.

Idol very high 3000rpm possable idol sensor


throttle positioning sensor voltage should run around 1 volt at idle. If you unplug the sensor the car should still run on the presets in the computer, this will turn on the check engine light but if the RPM's drop down to normal replace the tps.

Check engine light on,idols rough,fine at all other speeds.


It either has a vacuum leak or a dirty MAF. To test for vac leaks spray the engine with carb cleaner to see if the engine speed changes., if it does you fond the leak. The most common leak is pcv line coming straight off the back of the throttle body. Check there first. Also check to make sure there are no air leaks between the throttle body and the mass air flow. Don't replace the idle speed motor or the tps, they won't fix it. It is possible the o2 is the problem, but it usually isn't. P0107 Is usually always from the stuff i listed above.

I decided to check the idol air control valve,when I removed it I found the problem right behind it. The P C V valve hose was just about into where it fastens to the intake,the other end was bad also. Cost me aout $6.00 Where auto parts stores were telling me parts would cost two or three hundred $$.
