Missfire??

P0301 Cylinder 1 Misfire Detected
My car through that code 2 days ago, i checked it today with my cobb ap. The car seems to run fine... when the code came on the car had a rough idel. Its happend before as well it just went away and came back. I finally had a chance to see waht the code was today. So what do i do now? Take it in? i have a TBE and ap map on it... could it be a bad injector? And will warrenty cover this?

Might be some bad fuel you got at the station.
You have different blends for different seasons there do you not?

try changing the plugs and reset the ecu.. see if it improves..

I've got a question, a mechanic told me that I seem to have a misfire at higher rpms, yet I have no CEL, is that possible?? (car seems to rev smoothly..but feels slow)

also, what map are you using? Is it a cobb off the shelf one, or a custom tune? if it's off the shelf, is it the california map?
