Wow willwren, thanks for the offer.
I don't own the scantool, just rented it.
1) Still keeps throwing code 13 despite new AC Delco O2 sensor. Will try relacing wiring between sensor & PCM this weekend if I get time.
2) Now that weather is cooler, not getting code 17 very often but my wife had one day last week sitting in supermarket lot >1 hour because no start. She'* NOT HAPPY
!!Obviously Cam sensor was not the problem. Have ordered AC Delco Crankshaft position sensor. Any tips on alignment at installation?
3) No code 58 since disconnected tumbler tamper switch. It would sometimes go weeks though before throwing a 58. Is there anything can be done to repair the switch if that was it?
I just pull the codes by shorting the terminals at the underdash connector. Real pain.
