Help with Engine problem

E93FTW · 10-21-2014, 07:26 PM

Hey guys , this morning my car gave me the Check engine light,rough start,feels like a tractor,loss of power, vibrates a lot. I used an OBD scanner and gave me code P0304 and another code that came back NA. I still have CPO warranty and 46000 miles on the clock. What could it be? Am taking it to dealer tomorrow most likely. Thanks

Yeah that's from a misfire. Looks like your coil in cylinder 4 took a hit. Now when one coil goes the rest are soon to follow, so your best option is to replace them all and do the plugs too if you haven't done them yet. Although you are under warranty so in this case let the dealer deal with it.
