ok, so i took off my basanni off road X pipe and put my stock h-pipe back on, unpluged the batt to reset the comp and drove 50 miles......and my CHECK ENGINE light turned on again? what the heck......i need to pass smog and it will not pass w/ a CHECK engine light on! what should i do now?

 

O2 sensors attached and working/plugged in?

 

Welcome to the forums... If it's not the O2 sensors, post your question in the model specific forum for a better response...
