[RESOLVED] Running like crap...any ideas?

[AWDTSIer]

Ok so i have this issue which i think is in the fuel system somewhere. I replaced the filter today and yet nothing. Under a load it misses so bad, spits and sputters like u would not believe! The whole car jerks and it has actually stalled twice while driving down the road. It is through the whole rpm range, but yet with no load it runs good, doesnt hesitate at all. Any ideas?

The light comes on while i am driving down the road, it goes rite back off though. also i did a little expierimenting today on my way bak from work, i unplugged what i think is the TPS, its the sensor on the top right side of the throttle body, and it ran decent, only missed for a second then it wld run fine?

The ECU will store the code until you either clear it out with a datalogger or until you unplug the battery for a few minutes. You should check your air/fuel ratio as well. Do you have ANY type of tuning/engine monitoring hardware like a logger or at least an A/F ratio gauge? If it bucks its because you have either huge vacuum leaks or you're running a hacked MAF and not compensating for it with an AFC whether it be old or new style (do you have one of those?). After you check out everything else including fixing boost/vacuum leaks, plugs, wires, PCV, valve cover breather, BOV recirculation, then worry about making your air/fuel or oxygen sensor voltages cycle back and forth. Any manual whether it be Haynes or Chilton's will tell you how to pull ECU trouble codes. You will want to use (roach clips) and attach them to the two appropriate terminals. Then you attach an (analog) meter and count the sweeps of the needle. If it sweeps with two short ones and then three quicker ones then you have code 23. It will output all the stored/active codes as such. Take your time with it and dont shortcut/skimp on anything.

Problem fixed...Thanks guys! It was the throttle body, cleaned it and installed new gaskets, runs great!

boost leak test solve so many problems well lead up to the solutions that is
