    Car was running fine for 6months, now all of a sudden after about 10secs of idling car starts to surge till it dies. It seems to be running super rich compared to before. It seems to almost be loading up like a 2-stroke. Its got to be sensor related. So far Ive replaced the IAC, and MAF sensors whats my next sensor I should replace. Cars all stock except for the incon kit.

    i assume you've already checked everything over for vacuum leaks? that is one thing that would cause it to do what you've described - even running rich. if there was a leak and the vacuum was lower than usual, since the fuel pressure regulator is vacuum sourced, it would be running more fuel pressure than normal. it'd explain your surging problem too.
