Ok I re read. I don't know what the voltage on your ckp sensor should be. My early post was wrong. In mine I know it should be .5 volts ac (not .05). The fact that you cranked it with the cam indexed off could be an issue. Do you know how far off it was? The only way to know for sure is a compression or leak down test. I think more then likely its one of the two sensors. Probably ckp sensor.

Hate to bring back an old thread but I finally was about to give up on my engines stumble when everything tested good including the crank sensor but I decided to replace my after market replacement with and oem and guess what everything got better. Point of the story spend more for oem because after market obviously sucks like everyone states. Thanks
