Cleaned TB and replaced ISC. Car still idles like crap.

Well over the weekend I took off my throttle body, cleaned it, replaced the ISC(tested bad) and my car is still idling like crap. The check engine light has gone away, but it still idles pretty rough. Should I look into getting a tune-up next to see if that helps?

what do u mean by idling like crap? High, low, jump?

It idles around 800 like it's supposed to, but it's real rough.

How's your vaccum? Check your intake for leaks. That extra air escaping can have a decent impact on the quality of your idle.

my injectors were nasty ass dirty... and my idle was pretty rough. I ran some fuel injector cleaner through it and it smoothed it out a lot...

of course my idle was still ####ed up... but it didnt die, and the idle was smoother...

Check your tps sensor as well to make sure it is not loose.

ALSO...im not really sure if the idle would go up or down but I know i adjusted my barometric pressure when my idle was screwed up and when I had the pressure at the wrong place it idled REALLY rough and like crap...So i did wat vfaq said and it straightened it out

my car idles like shit too. i ran injector fluid like 4 times already in the past 8 months, and its still crap. i have a feeling it has sumthing to do w/ the idle sensor, or water in the tank.
