After a failed TKO install I got sick of my Mustang sitting for 4 months, so I put in a King Cobra clutch. Beforehand the car was idling a little bit rough, and drove a little bit rough at low rpms, but no hanging idle. Now the car idles really rough (~1100rpm compared to 850rpm) and the idle hangs really bad off throttle and down shifting. I still have good power (compared to what I remember), and its not blowing any smoke.
I figured it was a vacuum leak, checked with carb cleaner but didn't find anything. I tore off the whole upper intake and found that one bolt had been stripped out. I found a longer bolt that managed to hold the rest of the threads and could be tightened down pretty good. I put everything back together, but the symptoms still remained.
Took out my JMS chip, same problems. Ran codes and found nothing.
The only thing that I can think of is that something is leaking around the mass-air meter. Thats in the fenderwell because of the AFM power pipe, and I don't have my lug nut key to get the wheel off and look in there. But I looked through the hole in the fenderwell and everything looked normal.
Anyone have any suggestions or ideas? This thing is running really rough and doesn't sound good.
