First problem is that when i drive my car and shut it off and then go to turn my car back on it starts to rev up to about 4000 RPM and and back down to about 2000 RPM and repeats this process for a few minutes. I have replaced the throttle position sensor, 02 sensor, ECU, and cleaned out my Idle air control valve. When i go to shut my car off when it starts reving up high i cant start it because it floods itself with gas. The check engine light DOES COME ON.
Second problem is when im driving my car tends to surge. Its not the distributor because that has been replaced as well as spark plugs. Im thinking all this is connected with the fuel system in some way. I am completely lost and do not know what to do. Any help would be MUCH appreciated. Thank You
