Default EFI questions
In the past few weeks my 302 EFI has started to run funny. The engine is a rebuilt 89 GT motor with a c-303 cam and Cobra R intake and computer, MSD ignition T-5 transmission. About 5 or 6 weeks ago it started backfireing when I downshift. I installed new manifold gaskets but saw little if any improvment. Now the car is starting to Idle iratacily and die sometimes when I stop quickly.
I have about 5500 miles on the car and until these problems started I had no problems with the car. It seems to have plenty of power and feels fine when accelerating and cruising but it is really starting to bother me.
Anyone have any ideas?
Thanks
