Rough Idle??

ImportKiller · 01-17-2003, 01:56 PM

I've noticed in the past several weeks, my mustangs idle has been very rough, so to the point that it shuts off....i notice this happens on cold starts and when the engine is warm from driving around town....

My engine is mostly stock with the exceptions of the exhaust system jba headers, bassani x-pipe, and mac catback....

i've heard this is a common problem and that it might be my K&N filter could be dirty, does anybody have any other ideas of what might cause the idle to act like this...

Sounds like your mass air is due for a cleaning. It wouldn't hurt any way.
