Hey guys, I have a problem in my 03 cobra and I need your help, I have gotten the code po148 (fuel delivery error), but my check engine light is not NOT on! And At high rpm's around 5-5.5 my car just falls on its face at WOT, then about two seconds later, it picks back up. Its Mainly when in 3rd or 4th gear pulls. I've changed the alternator already so it's not that. Could it be the fuel filter, fuel pump, frps?? Any information would help guys! :shrug:
