Anybody check they're o2 sensor connector? I tested mine with an ohm meter and its way outta spec. I'm not sure if this means the sensor is whack or the connector. (I have one of the sensors from MDC and had to splice the new sensor onto the old connector.)

iam not sure about the codes, but i had the same problem. my fuel pump resistor was unpluged. pluged it back in and it started right up. hope this helps.
by the way if you don't know where to look. it located on top of the right hand fender well. its the little metal box with heatsinks on it. good luck.

I have the 12v mod so the resistor is by-passed. Mine wouldn't switch to 12v in high end anyways.

Does anyone think this might be a battery/alternator issue. Both my battery and alt have never been touched since I have had the car. (2yrs)

i have the mod too, but if you don't complete the circuit(or you just have a bad conection) it will start..run for a sec. and then die. its not the battery or it wouldn't start in the first place. i'am pretty sure its not the alternator. even if it was, the motor would still run until the battery died. then you'd have to charge it before it would start again. good luck.

welp guess I didn't have a good connection with that 12v mod. Unplugged the jumper and plugged it back into the resistor after jiggling the wires and she started right up. Thanks antman for jogging my memory!

I am having the same prob. COde 31, on and off all the time. Soon as it goes into boost.....it feels strong....then kinda dies off even thought the E01 says I am holding boost.....then let off......check engine light and it starts chugging. At the lights.....it doesn't seem to want to idle.
