I have an 06 civic si and I went into the store came back out and the car stopped running right. It sounds like it is misfiring and is idling at 500rpms and has a big loss of power. Does anyone have any ideas or any thoughts let me know....

 

Welcome to the forum,I would first pull the codes and see whats up,if all is well there it may be a dirty Idle Air Control Valve or possibly a dirty EGR. Start with the simple things first.Good Luck ,Bobby

 

Thanks for the info I'll try it and c what happens
