Before you go buying used TB's and ISC's, check your current parts.

From another thread:
Ok...thanks to awesome people on here...take the intake off the throttle body and look inside about bottom right, and you should see a little square hole....stick your thumb over it, striving it of air...if it idles properly then its the isc valve.

If it is faulty then it is possible to clean it.

The only way your TB could be bad is if the brass butterfly is worn down and allowing too much air to pass at closed position. Visually look at it and move the butterfly side to side.

Ok guys im looking for a ISCV ..... I bough one off of ebay, but it ended up being a different throttle body.. Possibly from a 93+ or celica because there was no Idle Speed Screw... Let me know if anyone has just the ISCV.. Thank you.
