Ok , so with the new EBL system in the computer, I've been trying to get ol' whale started consistently, no stalls or near stalls, nor three and four times at the key till it finally but barely keeps runningcatches. So I figured I'd better start from scratch again and loaded the start routine from the stock Calibration back into the ECM.
Forgot it was there this morning. Oh crap! This is gonna hurt!
Cranked it over, caught right away, stayed running, no stalls, non shuddering on it's way to stall, Nice smooooooth idle.
Damn Smart aleck GM engineers
What makes those jerks think that with millions of dollars, state of the art diagnostic equipment and test tracks, that they can do something better than me with a laptop, a few day old donuts and a glove box full of tow truck receipts!
DAMN SMART ALECK GM ENGINEERS!
