So I did all the main problem checks: cleaned the air filter and put a new IAC on and it still rough idles and dies sometimes idling or when the clutch is engaged. Does anyone have any idea on what else it may be? It has a BBK cold air with BBK filter and BBK 70mm throttle body along with BBK full length headers to mid pipe to two chambers. If anyone knows how to correct this problem, I'd appreciate it. Getting tired of having to constantly start my car.

Have you replaced the plugs? I had a bad idle and overall performance. I did a lot of things till I finally replaced the plugs and it cleaned up my idle considerably.

Get fid of the fenderwell CAI. I still think that's my problem but it's so damn hard to get the MAC filter back on. That I am just driving w/ a rough idle. If there's a leak somewhere, it'll idle rough

You can also try cleaning your MAF sensor and resetting your PCM

Is there any particular cleaner to use to clean the MAF sensor? I think I'll try that before going the
spark plug route.
