Not clear what you mean in the first few sentences. But regardless it's not clear if you've actually checked the ISC (aka IAC) yet.

If you haven't, you should. It functions as a choke when the engine is cold and if it's not working properly your engine will run like crap until it warms up.

The Factory Service Manual has the procedure to test it (you have downloaded that right?) All you need is an ohm meter / multimeter for the test. <img src="/forums/images/graemlins/kewl.gif" alt="" />
