now heres the kicker I was hammering on it this evening just now after I did this nice hard pulls untill around 5K and it stumbles but then keeps going but when Im around 60 in 2nd gear I get a SES light.

checked the code and Its damn 61 secondary port throttle system WTF
The old code 61. Don't you love it. Secondary port throttle failure seems to be the most common problem that I read about on here. But I'm sure you are already familiar with the method for chasing down and fixing that. When it happened to me I don't remember my car shaking. But I do remember it running out of breath at 4500rpm's and then the ses light and the H61. The secondaries weren't working when I bought the car. And at that time I knew nothing about the car. Let alone how to fix it. But I found an article about secondary port throttle failure on the corvette action center "with pictures. I like pictures" and it really helped me understand how it works and what to check for. It took me a month to close in on the bad component. And just when I was about to throw in the towel thinking I had made a big mistake buying this car. I found it. A $36 part causing the problem. It was the secondary vacum solenoid. Buttoned the plenum back up and for the 15th time took it out for a drive and crossed my fingers and prepared to mash that peddle. Wow! What a difference. The rest is history. I hope its somthing simple like that.
