Hey all,
I'm new to this form but at this point i'm getting pretty desperate and don't know what to do. I bought the car back in march, ecstatic that i got such a great deal. I paid $1,000, it was a mechanic's car who was out of work and needed the money. At first all was well. Then I began to notice it would shift and start very high, I'm talking cold start at 3,000 - 35k. Idle at 3k. When driving shifts out of first at 65k then stays high until second at 70k or 65k what ever it feels like, shifts smoothly though. I had an older friend who used to race old muscle ride it and he told me that it probably isn't the tranny, but more likely the tps. I know it probably doesn't matter but, i replaced the pcv valve, air filter, and fixed the cruise control (a vacuum hose was split). I have not changed the tranny fluid, oil, only flushed the radiator coolent. After riding for about 30 mins at 55+ the check engine light comes on. I used a jumper to check the computer and the computer continuously flashed 12. Which according to all research I have done is normal. I know there is a problem. But I do know what it is. Before i order the TPS, which apparently no one carries, i would like to get a general idea. Thank you in advanced for reading and any advice and help.

I recieved a very helpful email from n0i and it seems like it's going to be either the IAC or the TPS. So that may solve one problem, but another one comes up. What would cause the car to sound like ti's whining when i press the accelerator. I have had belt problems with other cars in the past, and this is not belt whining. It's almost sounds like an electric engine.
