Just started happening. The car is a 75 2.0 with fuel injection. It has a pertronix ignition. The problem is, it seems to be jumping up and down in the rmp's and idles very low. Idle adjustment didnt seem to help. I checked all the grounds and contacts including the tranny strap. I swapped out the voltage reg and throttle switch and the problem still persisted.
Computer problem? Timeing problem? timeing was done last year, fi trigger points a few years old. Pertronix problem? its about 4 years old Bad coil? 4 years old Grounding issue? has new fi harness from bowsby - 2 years old Head temp sensor? its about 2 years old. What would you all suggest. Thanks for the help, Tod |
