Hello 2carpros! I have a problem. When I drive my car, the cars Rpm raises alittle. But when that does that, my speed increases. Even when i dont hit the gas pedal. (Example: I pulled up at a red light and, I had my foot on the break and out of no where, my car wants to take off!) Also, when i drive, i dont know if its the transmission or not, but, i hear a *Thump* sound when i hit the gas. What is that? If it helps, my car died in the middle of the intersection and my fuel pump went. I replaced it and it still does it.
