We were traveling at about 70 mph on the freeway when a check engine light came on. We looked for a wide spot to pull over and probably travelled 5 to 10 miles more before pulling over. During this time, the engine got a little louder and was missing. After we pulled over, I found that the #3 cylinder had blew the spark plug and burnt the coil. We had it towed to an oreilly's auto parts store and spent a few hours at night trying to fit it. Fortunately, in the morning the manager was able to locate a spark plug rethreader tool and inserts which I used to fix the cylinder. I also replaced all the other plugs and found they were all loose. I had purchased the truck In April 2019 and had done the timing belt/waterpump and all the ancillary belts, tensioner, fan clutch, fan bracket, radiator and such but did not check the spark plugs because the truck was running great. We had used it to drive to the Arctic Ocean/Alaska and home to Virginia in June/July without any problems.

After my parking lot repair, I was able to drive 1400 miles to home The truck ran great and I thought that I would not have any more issues. After about a week I noticed a metallic noise coming form the driver side of the engine. It sounded like a bad lifter or bearing. Long story short, having the engine replaced with another 2006 engine with 130k to replace my current engine with 275k.

Check your spark plugs and make sure their torqued or snug depending on how you do them. OP hopefully your engine does not have any other issues. Please update us with your fix. Good luck.
