So I had a problem with the check engine light and decided to take a chance on the O2 sensor, the plugs and wires are all new. The check engine light has been cleared and after a 20 mile drive it is still off so I think the O2 was bad. Now my current problem that remains is I have a ruff idle. When I come to a stop the car revs down to 1000 rpms and then a few seconds later down to about 700 rpms and it gets ruff at that point. Now I'm thinking one of two things, one try and find a new idle control sensor at the junkyard or two, on the TB there is a screw stop for the throttle if I adjust it the car will idle at a higher rpm. Now is that the way to go or should I go a different route. I don't want to keep throwing money at this just guessing.

specs: 2001 SPI 5 speed MTX

No need to guess about vacuum leaks. Get a spray can of carb cleaner, and spray around all the hoses and gasket areas, while the car is idling. Avoid the spark plug/wire/cap area.

The smallest vacuum leak will suck in some of the spray, and the engine will speed up. If you work slowly you can pin-point the leak. Works every time...

DON'T DO THAT! You'll be in a world of hurt. The only way to adjust the idle is through the computer, either through a tune or through a dealer. I learned the hard way. Try checking off the dumb stuff first, before getting technical.

Because the computer controls the idle. If you mess with that set screw it will compensate for it and equal itself out to what it was before. After awhile the idle will get all screwy due to the fact that you messed with the set screw. I had about a 3 month or more ordeal with messing with that and just wished i would have never touched the damn thing.
