Help please - motor acting wierd, strange symptoms
'85 360/MC 2150/TF 727
Jeep just doesn't run well. It has started to barely idle. It hates warming up (start. die. start. feather gas. die. start - do this a few times, then it runs). Once warm, it runs, but it feels like it's barely running. Super quiet, but decent rpm. Just weak. As if the spark is weak. Then today I'm driving from the gas station, and it dies at like 30mph. I'm coasting in drive for about three seconds after it dies, then a HUGE backfire. I put it in neutral and start it. It starts right up, but still runs weak.
Assuming this is an ignition system thing and not a carburetor thing, the current ignition system is: Optima red top, standard Ford ICM, Accel wires, standard cap and rotor, standard distributor and special coil with built in voltage regulator (per the suggestion of a mechanic a couple years ago).
Would the TR upgrade help?
