[LEEVON]

This is why we dislike working on older vehicles in my shop. Parts are so hit and miss. Last cap I put on a personal vehicle was Napa/Echlin and is going stong, doesn't see many miles though. It does "feel" more substantial but of course you can't see inside of one. Coils are just as bad. If somebody brings us a GM vehicle with a distributor and they have been replacing parts, we decline service...there's just no baseline and not enough "known good parts" to start with, even if everything is NEW. We did get roped into a '97 Silverado this week, only because the customer thought it was the fuel pump we replaced last year. After nearly 6 hours of troubleshooting we found a wire harness issue, was frying the coil after an hour or more of driving.
