Hey all,
At about 2k rpm my car is bucking or surging. I've checked all the vacuum lines and they look good. I plugged in my trusty scanner and it gave me a code 33 and a code 44. I'm fairly new to all this electronics stuff so I have no clue. The code 33 is egr related and the 44 is thermistor related. Could an inadequate fuel pump cause this. I also noticed that on the track when I'm balls to the wall my engine tops out at 5k (works fine if I slowly accelerate). Also, my tps, egr, and iac are fine. Any help would be greatly appreciated.
