just go over all of the work you have done before you start chasing your tail around the truck.is number 8 the only cylinder missing now?you can always pull the plug to make sure its not cracked, or gaped wrong dare i say...I once had a number 4 misfire that came back a week later with the same code after i fixed it with a tune up.I could of started chasing my tail doing comp. tests and swapping injectors, but instead i pulled the plug only to find out i cracked it during the install with my air ratchet (never made that mistake again).remember it ran fine for a week!
