Hey y’all, I keep getting a p0300 code on my 2005 3.8. This is a random/multiple misfire, no specific cylinder codes. Replaced spark plugs and wires (all needed to be replaced anyway) tested each ignition coil and the ignition control module, all of those work fine. Also did an electronics test on each wire to see about timing, the 2356 cylinders were all receiving power on time and in time, the 1and4 cylinders are not receiving power, these happen to be on the same ignition coil pack, swapped coil packs, issue remained in the 1 and 4 cylinders, like I said, those were the first things replaced. I have a bad engine shuddering problem, very low rpm, super low mpg and a smell of gasoline, not sure what else to try, I’m going to clean out the fuel pump and the throttle body and MAF, has anyone had this problem before?
