Been done for awhile now, just wanted everyone to know - mission accomplished! Thanks for the great knowledge you ALL shared!

Out of all the Dealers, mechanics, other Buick sites, and so on,
no one, no place, and no other site, compares to Automotive Forums! Thanks!

Cam sensor and magnet are replaced, cleared codes, still having an issue. But something else set off an issue.. I wash my engine every year and it's been fine so far. But this last time when I started the car it seemed to be missing bad and stopped running every few minutes. I eventually made it home and found that the issue was a weak coil. Ran fine for a few days and then I accelerated hard (I don't drive on highways often) The car missed once and then stopped running and since then has had the problem of running a few minutes, stalling, running a few seconds, barely firing, and then no spark. Replaced the crank sensor and it worked fine for a few days on short drives, then I got on the highway again.. Same hard stall, and then I had to wait nearly 15 minutes between startings just to move a quarter mile at a time. So I have my harmonic balancer off again, checked resistance between the sensor and ICM and it checks fine. The crank sensor has some wear grooves, but from what I've read that's pretty normal. I have a spare ICM that I changed out, but the problem persists. I'm almost ready to get a dealership diagnosis or re-wire the car myself, but I lack that kind of money or time. For the record: New fuel pump, filter, and pressure regulator a few days ago and good pressure at the time. New alternator a few weeks ago as the last one was failing. Tap test turned out fine on the ECM.

And today: New CPS (not a cheap one) and Harmonic Balancer, no rubbing, and dielectric grease on ICM, crank, and cam sensor plugs. Code went away for about 15 minutes and it ran better than ever.. then it stalled while I was inside getting a drink and now the code is back, wont spark at all, even running the backup ICM after 20 minutes off. I've checked all available fuses and the pump cycles when the key is turned. I don't have a noid light but I know my pressure is fine. I'm rather open to suggestions.
