hahah yeah I have no cats. I have been through this car so many times now I did find a partial wire melt but it doesnt look like its gone any further then just the black plastic cover for the wires..It has an appointment at New Era Performance for wed. Im getting to that point where Im willing to eat the cost to have it work right....just in time to go away for winter considering there were snowflakes as I drove it to the shop to ask a few questions.

Loss of compression isn't always uniform between all cylinders. There have been plenty of posts here with only one or two cylinders low. #1 is a pretty easy one to check. If that's not the problem, it's only cost you about 15 minutes time, and then you can focus your efforts elsewhere. Sometimes diagnosis is a process of elimination.

The shop that had the car apart does a lot of Corvette work, and would have hooked up the O2 sensors correctly? Did your scan show anything unusual about fueling?

I NOW HAVE THE ANSWER TO MY QUESTION!!!!! I got the call from New Era Performance today on what was wrong with my car after much troubleshooting on both our parts. The problem was.....The ****ing transmission shop hooked up my 02 sensors wrong, as in the front 02s were hooked to my simulators...which is bad news bears. BIG thank you to new era performance and to all who responded, you helped me narrow everything down and save a lot of money!
