yea it wouldn't say the code was for my stupid gas cap also a vacuum leak and it just said major misfire wouldn't tell us much more we put ac delco plugs I think the copper not sure took it to my regular car place they said that the things I said above in my post were the cause they wanted 200 $ just to replace a coil pack that they were sure that was the cause so we went and bought 3 just to see because we were not sure which one was bad but none of them were so I took them back and got my money so im lost on what to do I just paid this car off
