major problem on my motor
came from the coast this pass sunday. on the way home my motor started shaking the next thing you know i started losing power. I pulled over at the next rest area i check the sparkplugs and all four on the driverside were loose not knowing how bad they were burn i just tighted them up and turn the truck on. it stayed shaking but i needed to get home before dark ,because of my kids, so i forced it all the way home. as soon i got home the truck turned off and that was the last time it turned on. i replaced all the sparksplug because the four that were loose melted on the tips. it still dont start but i check the oil because the oil gauge didnt move and it smelled like fuel! i hooked up the computer and it told me that cylinder 1-4-8 were misfiring but i have no clue. it didnt smoke it didnt knock. please help me with your honest opinion thanks for taking the time for reading this!!!!

I assume this is a Ford truck with a mod motor right?
Misfires on 1, 4 & 8 are opposite banks. 1 & 4 is on the passenger side and 8 is on the driver side.

It's LOUD but YOU looked!

do a compression test and check your plug threads.
4.6 are known for blowing spark plug threads. if you did you will have to have thread buckets put in. (rebuild)
