Accelerating by itself?
Alright, here'* the deal. I got a 93 w/ 150K miles. Car has been great up until the last few days. When i am in park, i can hear the engine accelerating and deccelerating for a few minutes. When i shift to drive, it jumps as if i was accelerating. It can go pretty fast w/o me even touching the accelerator (2nd gear at least). When it suddenly stops self-acceleration, the check engine light comes on. the shuts off quickly. and its back to normal. These occurances are very random and can happen at anytime. Also, at red lights, it is a very rough idle with sudden jerks at times w/ the car accelerating itself again. Any details that I have left out? How can this be fixed? I think it may be a sensor but i'm not too sure, and i'm not that car savvy. Also i don't know how to get codes on that car so if anyone wants to provide some DETAILED intructions preferably w/ pictures, it would be helpful (same if it is a sensor that needs to be changed). Thanks
