Git-up-n-go problem

[Chrisr]

Well, I guess it had to happen sooner or late, my first post with a problem. Here goes. (Hope C4C5specialist is out there)

Couple of weeks ago I took the pride-n-joy to the beach. About a 65 mile trip 1 way. Car ran great, air was cool, couldn't ask for a nicer night. About 3/4 of the way there, I get the dreaded check engine light. I eventually come up to a restaurant, pull in, and turn the car off. I let it sit for a few minutes, start it up and all is fine and I continue to my destination. Now, I did get into the throttle for a bit, but nothing harsh. No, I had a brain fart and didn't check for codes.
A couple days later on my way home, I have to stop for a traffic light. I stop, it turns green, I go, but at about 1300rpm the engine feels like it's not getting gas or 4 of the 8 injectors or cylinders just cut out. Check for codes this time and nuthin'. Almost as if it's being limited/retarded somehow. I pull over, blip the throttle and all is fine again. This problem has been happening only when I start out from a stop or slow roll. Doesn't matter if the engine is cold or hot.
Took the car to the dealer last Friday. Thank goodness I have the GMPP!!
They had the car all day, reproduced the problem at their will and nothing shows on the "Tech 2". Replaced "pancake" switch in tranny, tried a new tach module, checked to see if I had bad gas (in the car), nuttin!! Now the tech 2 did show something to the effect of the tranny switching from park to neutral while the car is in motion. The problem doesn't seem to be as bad now that I have it back. Car still isn't fixed, couldn't leave it over the weekend. Car goes back 8/22 so the dealer can have it longer. One of the tech's seems to think it may be a valve body(?) in the tranny???

Sorry for the long drawn out explanation, but ANY help would be appreciated!!

Thanks!!

HI there,
I would need to know the trouble codes in the PCM.
This would be the first course of action.
Allthebest, c4c5

Thanks for the reply C4C5. I don't have the codes, but I could get them from the tech Tuesday when I drop off the car. I'll post back then with them.

Chrisr-
You can get the codes that c4c5 was talking about yourself from the Driver Information Center (DIC).

Thanks Jim! When I took it in Friday, there was one history code that happened 194 miles ago. The thing I have to do now is drive the car and hopefully get the check engine light to come on and throw some codes. Sounds wierd, but at least I get to drive the car!!!!

On an off topic side note: I'll be away this weekend, but when I get back, I would like to get some info from you on my Mom's chemo. She's handling it very well, but I ould like to be a little better informed.

Just in case any of you were sitting on the edge of your seat waiting to find out what happened with my vette. Here ya go!!!!

To make a long story real short, they replaced the mass air flow sensor due to a carbon build up. Everything seems to be A-OK right now with the car!!!

I gotta give a huge plug for the service department at Classic Chevrolet in Moorestown NJ. They were relentless in trying to diagnose the problem. Thanks Gene & Dom!!!!!!

Nice to hear at least ONE dealership has a decent service dept.!
