I recently had an entire set of glow plugs go bad after about 6000 miles of use. They were all replaced with new Autolite GP's because that is what I had available at the time. Within about 4 months one of the plugs went bad and I dealt with it by ignoring it and using the block heater. It finally got to the point it did not want to start even with the block heater and I pulled them and replaced them, all of them were bad, as in no resistance at all.

Anyway, I badgered the parts store into replacing all of them for free and now 2 months later one has gone out. I am going to replace them with the bosch replacements before winter sets in.

However one of the people I talked to about the issue mentioned that he had seen this type of problem occur when the IP timing is offf and causing predetonation. Basically the shock of the predetonation was killing the GP's?

Has anyone heard of this type of problem?

The car runs like a topp and I would expect that there would be some performance problems if my IP timing was off enough to cause predetonation.

Maybe he just wanted to sell me another set of autolight GP's

Thanks,
Stephen
