Could it be the coil? Because my shift light which I have wired directly to the coil is cutting in and out too.I figure maybe it's on it's way out. Any ideas?
18mustangs said:Chris, do you have an aftermarket tach? If not hook an aftermarket tach up and see if it does the same thing. My factory tach freaked out on my car and runs backwards most of the time while occaisionally working correctly. I just got a nice Autometer tach and love it.

HISSIN50 said:No similar experience with that, but a weak coil will start to show up at those RPM's (you are not the first to report that issue and then have a new coil fix it).
Sorry to not have firsthand experience - just recollections from having read 100,000 threads.
Good luck Chris. Besides, a new coil will look nice.
CManT1914 said:Thanks JT, now I just gotta scrounge up that thread by Ernan about coils. There was a poll with what coil everybody was running, the results were overwhelmingly in favor of the MSD I think.

HISSIN50 said:Uh oh, Ernan is bored again. I remember the last time this happened.
It was Ernan bringing back threads from years before. I think someone started a thread about him about doing this (that stuck in my mind).CManT1914 said:What happened JT? All of the sudden I just see "Last Post: Slow5.0" all over the boards, lol.
