So I replaced my plugs, gapped to .054, wire, dist cap and rotor, and changed fuel filter…… the plugs I removed were autolite and the wires were Ford racing, I replaced everything with motorcraft parts. Car was running perfect , took it out for a long run and it randomly shut off at 50 mph…… Rpm’s drop out and it dies…… key off and re crank and it starts up and continues on until the next time it dies. It’s never done this before so I’m going to assume it’s something to do with the new parts….what would cause these symptoms?
New plugs, wires, dist cap and rotor, now randomly stalling
- Thread starter WhiskeyFoxTrot
- Start date
So some information on the car would help...year, motor, trans, mods, etc. Also, have you checked for codes? The CEL only illuminates for emissions related codes so non-emissions codes can be present.
Have you checked for KOEO and KOER codes? Remember you need the motor up to operating temperature to correctly pull the codes.
I'd start with puting the old cap and rotor back on see if it still does it, and inspect the rotor seen a few new ones pretty much falling apart after little useage. Honestly I avoid newer motor craft ignition parts now for old push rod stuff.. Could be something else failing but never hurts to try the old parts.
Run the engine in the dark with the hood open. Look for Lightning. Look in the slots around the coil too.
I’ll try that when it gets dark tonight…… I pulled codes and it’s alot of them…… koer- 41,43,72,54
Koeo-15,85,10,18,41,29,33….. the 72 has to do with the maf, and 54 w/ intake it looks like…… I did remove the intake when swapping plugs….. will the maf cause the car to intermittently fall flat on its face?

Not necessarily. The maf can be unplugged even, will just run like crap.
Edit: and by "falling flat" I assume you mean stalling out.

Lol….. I love this car but it drives me nuts sometimes…… I put the old dist cap, rotor and wires back in ……. Long ride and zero Miss or shut down ….. must have been an issue with the new motorcraft parts….. I’ll put some more miles on it and see if it holds….. next question, what does everyone recommend for cap, rotor and wires? Car has msd, stock distributor…. Should I do msd stuff or is there something else guys like?

I have always had good luck with accel...not sure how they are nowadays it tends to be available at your chain auto stores which is why its on the car to begin with. You have one of those msd boxes on yoir car?
now a days…. Was just curious what everyone is using

Ive never been a big fan of ignition boxes. Im sure they have their place for people trying to eek out as much power as they can but stock ignition works just fine. What mods do you have?
Car had it when I got it….. I honestly couldn’t care less if it’s there or not. It has heads, cam, roller rockers, cobra upper and lower, msd…. Not sure as far as injectors or anything else…. I’m not trying to blow it up so I drive it easy anyway. I just want it to be reliable and run decent for the time being before the motor gets torn into or swapped
