Well MT.....Driving home last night was terrible...I had to stop every 10 minutes to get the SES light to stop flashing....anything above 2100 RPM this time. I ended up taking it to a Chevy dealer near where I work to pay them the 90 backs for 1 hour diagnostics. He ended up calling me and telling me they couldn't find a problem through their diagnostics and belived it is an internal engine issue. The service manager approved shop time to pull the cover and ended up conclusing this is a GM engine warranty issue. They think the CAM shaft is off.....it should be fixed tommorrow with either a new engine or CAM under warranty. In the mean time thanks for all your help on this, I really appreciate your time to share your knowledge and experience with us fledgling mechanics.
In the meantime I'm driving a loaner purple lumina with red interior.
How is it realistic GM QA could ship a crate engine with a bad CAM shaft ??? At least it would explain why I had to slot the distributor clamp.
Thanks
Mike
