A couple weeks ago I posted about this problem, where my car surges and stutters at 70mph and above. I installed a new O2 sensor since my other one had been exposed to race gas but it is still there.
Its REALLY annoying, because I cant accelerate in overdrive. With the converter locked, if I give it a little more gas to speed up to 80, my boost starts to fluctuate between 0-5psi, the car has very little power, and it shudders slightly. If I give it more gas it goes no where. I have to let off the gas completely, then step on it and it takes off normally. I know it sounds lean, but I dont see how unless I have a faulty Thrasher (running a T-97).
It will also do it in drive at about 50mph, so its not the tranny or converter I dont believe. Does the T-97 have a screwed up fuel curve? It is fine at 20psi and alky @ WOT
