I am not new to this forum because I used the resources in it to rebuild and enhance the 2004r that I swapped into my Chevelle but long story short, I purchased a 1987 G-Nat and it was all good and great until one day it started to stumble and died, it would crank but not start....I looked around under the hood nothing seemed to be out of place didn't touch anything and closed the hood....tried to start again still no start just cranking....don't ask me why but I opened up the passenger side kick panel and looked at the ECU/ECM (not sure the difference lol) anyway the lid was missing to cover the chip and I removed it looked at it and put it back...tried to start it again and it worked.....now...the car still does this randomly shuts down out of nowhere (engine light flickers) and so far a couple of light taps on the passenger side kick panel fixes it right up, to me it feels like a loose ground but the ECU/ECM was (and still is) wrapped in a heavy plastic bag and none of the wires from the connector look like a ground that would be near the connector.
I have also noticed that right after this happens the car seems to run extremely well, it has happened cold and hot and it is just getting annoying.
I don't have a scan master (one is on the way) I did use one of those $30 reader plugs and I got six time code 12 so based from the tech pages means all is good (which could be false if the ECU/ECM is loosing ground)
Any help is appreciated.
