the check engine light flashes, but you get no codes... thats not right.

start with the basics, tune up, how long ago?
list everything youve done in the last year, as much as you can remember.

how does the exhaust sound? got a whistle, when you romp on it?
most idle issues are due to a crusty IAC, look that one up in the google bar above the threads in the tech forum, how to clean. or replace.
also make sure your not suffering a vacuum leak,

id suggest running it by a=zone and see if they can pull the codes for ya, and get a copy of what they get, then post up.

bout all I got, gonna need some diagnosing out of ya before we can narrow it down, good luck!
