Ok so i just got in tuch with the guy who programed my pcm this is what he said:: "I checked the file and the VATS is disabled. There is one thing that is enabled called "Data Stream Fuel Enable", which is just below the VATS. My car doesn't have it selected (but has the Y-body VATS selected, go figure) so that could be causing the problem. If you can send it back I can try taking that out... Other than that I am clueless."

Any one know about this? is their away i can disable or enabe this w/o sending it back to him or does this sound like it could be the problem?

 

check the ohm output of your temp sensor on the water pump.

if you've been in touch with the programer you must have had the info from the scan test and data stream annalisist to talk to him about???

y is corvette body, but that still won't change much ... for the vats , it's disabled ...
as for data stream fuel enable ... wish i had one i could try.
need to get some info from a dealer about the programing options.

 

Have you figured anything out yet? I'd like to know if you resolved your issue as I have the same problem.
