[s13silvia123]

i was driving back from walmart. my car buckles and then backfires really bad. i know that i'm running a little richer than i usually am. could it be my sparkplugs are bad or is it my O2 sensor went bad. then i recieved my Power FC switched it in then it ran fine for the rest of the day. what could be the cuase of it.

Could be small boost leak or just running rich. Im battling a similar problem. Did you ever get the diff problem fixed? I still havnt had a chance to get you a pic. Its been raining.
