i have a lot of check enginge codes, how do i reset them and start over...some might be on there due to what i have done to the car recently (xpipe, cold air intake, and so on)...

i did find an exhaust leak near the driver side o2 sensor and tried to fix it tonight.....if air was getting to that o2 sensor and it was measuring lean, could the o2 sensor make it run so rich it would die....????
thanks for the help, bob

32 is DEFINITELY too low. This is with the engine IDLING, right? Now just priming the fuel pump? Stock SHOULD be about 40. At 32, you would run substantially lean. Maybe a bad fuel filter or a failing fuel pump could be the culprit.

The simple way to reset the codes is to disconnect the battery for a few minutes. That will reset the computer...along with your radio presets.

If your fuel pressure is only 32, I find it EXTREMELY improbably you're running rich at all unless your ignition system is ridiculously weak. Sounds like it's stalling from LACK of fuel then, and the code could be from a failing O2 or caused by the exhaust leak. Old/failing O2's throw all kinds of rich/lean codes that aren't accurate.
