Hey guys - seems like when I get a problem fixed, some new symptom keeps coming back. First here's my orginal post to the problem.

Ok now I'm driving down the highway doin about 70 mph. I let go of the gas going down a steep hill because my exit ramp is just ahead. All of a sudden my rpm's started goin crazy. It was bouncing from 500 to 3000 extremely fast - up and down, up and down. The check engine light is flashing on and off, when the rpms would bottom out at 500 the light would come on and when it surged back up the light would go off. I put it in neutral to let it coast down the hill and it stopped doing it. When I got down the hill I put it back in drive, it started doing it again. But I was on flat road now and the friggen thing was surging so bad it was sinking me back in my seat. I get it home check for codes - nothing. I leave it for awhile and then try to start it - nothing. Just rolls and rolls. Then 20 minutes later, I start it no problem, it drives like there is nothing wrong. I'm at the point where I don't trust me car anymore, I don't even drive it to work because I'm afraid it will break down on the highway. Does anyone know what the hell would cause the surging on the highway?? Thank.
