Little history. Been fighting a P305. Put I new coil on it (BWD) as it was all they had in stock. Misfire cleared but returned. I installed a new plug there just trying to get the misfire to go away. It's cleared up but returned.. Today I pulled all the coils from cylinders 1-5 inspected them all and switched them around. I also pulled all the injectors from that side and cleaned them and reinstalled them switching them around. Went on a test drive. I still had a high speed misfire it felt like to me. Watching torque pro the whole time and having the "total misfire gauge on" it never registered a misfire. It would go to 1 then go back to 0. I know the gauge worked as I was setting it up last night I registered over 5k misfires sitting at idle in the driveway. After about 30 miles I stopped at my parents house to pickup my daughter and when I restarted the truck I had a check engine light and code "P0352". I assuming this deals with cylinder number #2?

I can look to see where the coil from 5 ended up it may be on 2 now I can check in the morning.

 

That SHOULD indicate a circuit failure of some kind with cylinder #2's COP. You changed the coil, but did you change the boot too?

 

Yes all the old coils got new boots. I also confirmed that the new coil is on cylinder 2 now. I will be taking it off and returning it. See what happens after that

 

Got the coil pack off and switched out. Have no more misfires as of now.

It did jump on me at a red light and then die on me at low rate of speed about 20mph. It fired right back up. I will continue to monitor it see how it acts.
