My son and I replaced the crank position sensor, harmonic balancer, water pump, supercharger isolator and belts. The balancer had a long crack in the rubber, and we all know how noisy the supercharger gets over time. The old water pump bearing was starting to feel gritty, I'm amazed it lasted this long.
So . . . it hasn't died since replacing the crank sensor, but I've only driven it for an hour. My son is out of town for a week so it may not get much drive time. When I tried to get it to fail again (before replacing the sensor) one thing I noticed was the engine would sometimes cut out for less than a second under acceleration. It still does this with the new sensor. Does the engine die leaving the driver stranded with the new sensor? I don't know yet.
Is it likely the lack of crank sensor calibration procedure being performed could be an issue? Other thoughts on this momentary engine cut out under acceleration? Any way to do the CKP calibration with non-professional-price tools? I have a 2009 Cadillac also so willing to invest in a capable GM scan tool, right now all I have is MXTools OBDII scanner.
