Another update. Took the Vette back to Larry. This time (with the new air bridge installed) he was able to work the idle out, and get rid of most of the surging. I was so happy with it when it was done, that I ended up driving over an hour down into Fredericksburg and back, just because. Although, on the way back, my fuel guage dropped to ZERO. I had just filled up with Shell VPower so it didn't make much sense to me. But I SEARCHED and found some Chevron Techron should be able to do the trick. Overall an awesome day.

 

Glad you got the issue resolved. Communication is key with your tuner. if they don't know everything that they are dealing with, it will just make it more difficult for them to get it right for you.
As far as the fuel guage issue, yes, it is a common problem with vettes. Putting in a can of Techron every few tankfulls helps eliminate this problem. Also, reset your odometer every time you refill the tank, and know what your range is when the guage operates correctly. Then, you can have a good idea of how many miles you can go before you are REALLY empty. Trust me, it happened a few times with me before I started using Techron regularly.

 

Yea, I figure I can get the gas guage issue resolved soon. Also, my tach has dropped to ZERO twice now since I've owned it. I'll just be driving along normally, and the tach drops. Actually, the first time the gas guage dropped, the tach did the same, at the same time. Any ideas?
