About 18mos ago I installed an Edelbrock TBI intake manifold. I'd previously had a problem with the original distributor "chirping/squeaking" and rust around the base of the rotor, etc. I'd pumped some Triflow into it, and that seemed to take care of that issue, but the engine had always had a slightly rough idle and I'd read via a GM tech, that cracks around the rotors were a common cause.
Figured that since I had it all torn down, I'd replace the distributor. Purchase a rebuilt unit at NAPA and turned in my original as a core (stupid, I know).
About 6mos ago, the engine died driving through a parking lot and wouldn't restart. I popped the air cleaner off and laid hands on all the electrical connectors, and then it started and ran fine. It did it again a few weeks later, and again started for no apparent reason.
Hasn't done it again, even on a couple of 5hr each-way camping trips towing the tent trailer in near triple digit heat..............until last week where it died on my wife, just driving down the street. She'd only got about 3/4mi and by the time I got there, it'd restarted and was fine. Again, fine ever since.
Talked to a GM trained tech that I respect and he immediately said, "ICM" And well, here I am, sporting some rebuilt POS from NAPA.
So, should I go with an AC-Delco unit, or with something aftermarket? I'm not big on hanging aftermarket unless it's really tried and true....and there's some actual benefit, and not just a wiz-bang bragging session.
Thanks!
