ggenovez Posted May 10, 2022 Share Posted May 10, 2022 Hi all. 08 4.7 giving me P0300 error and random misfires. Originally it was 1,3,5,8. I swap the coil from 1 to 2. Clear codes now I get 1,2,3,5,7. weird. swap coil and plugs from 2 to 4. clear the ECU, and now I get 1,2,3,4,5,7. WTF??? Ok, every coil I pulled was cracked. Figuring that distrubing them may be the issue, I replace 1 through 4. Starts up fine. thought I had it fixed but after the 3rd crank i get 1,2,3,4,5,6. clear the codes and let it idle I get a flashing SES light. check the codes, 3,4,5,6,7. UGH. I can use a little help with this one. Quote Link to comment Share on other sites More sharing options...
