John I took it to MR Goodwrench's advice when I took it to the GMC
dealership. They troubleshot it and recommended a TPI Plate Cleaning
followed by a Fuel System cleaning as well. I took thier advice and
had them do it. They told me they could not get any cold start
problems, or any problems like I explained; but still recommended this
course of action based off my cars explainded behavior. Well that did
not fix it. The next morning it went back to the same old behavior.
So they told me (Chevy dealership) to bring it back and they would take
a look at it again. Problem is they keep wanting to charge for a
troublshoot. Not sure if I trust them. This looks like a try. If I
get any more issues I will record it then show them. Kind of wierd how
cars develope issues only at home not at the dealership. Thank you for
the heads up. I will give it a shot.
