Since I've had the coils replaced in my car its been running great until recently with a very random issue...Its a V8 and runs better with this colder weather however very infrequently now a coil drops out or something, the car will stall out, but restarts instantly, usually does this when its idling, but very infrequently and randomly, it happened three times in November...My dash has a digital readout that doesn't tell me much information, only that the problem was with one or more coils...I have to get my code reader and see what the computer says, I just haven't done that yet because its happened so infrequently, I've procrastinated...I need to get it fixed before the problem starts getting worse, its electrical so yeah I'm sure it will start getting worse sometime soon, and posting about it will help remind me lol...
