Haven't checked the TPS voltage yet, but bought a code reader today, turns out I had a few codes, IAC valve, coolant sensor, which was my fault because I unplugged them whileengine was running, but also the fuel pump relay circuit was bad, pump is running all the time, which to my thinking would explain the rich condition and also the idle surge, if the motor is loading up with fuel at idle it would pretty much be flooding itself out. Correct? Also, the fuel pressure regulator is bad once again, I guess the pump running all the time is just building up too much pressure in the line and the diaphram in the reg is blowing out.
