If any of my 5.4 brothers could help me out here. Truck had new spark plugs put in by the dealer when I bought it 1 year ago. The past 6 months it’s have misfires on cylinder 1,2,3, and 8. I ended up replacing those ones one at a time as they went. Last week It started having a cylinder 4 misfire. So I decided to order a pack of jegs coils. They came in yesterday which was earlier then expected. I put the ignition coils in that I hadn’t replaced yet besides #4
because it’s so far back and I did not have the proper attachment to get to it. So I planned to replace it today. I decided to take it for a test drive and now the truck is driving a lot worse. Having random cylinder misfires. The truck also puffed some white smoke but not much. I checked to make sure connections were good, and they were tightened all the way down. They were all tight on there. If anyone has any ideas please let me know before I take spark plugs out or take her to a mechanic and spend a fortune.
