sure you got the plug wires in the correct spot on the rotor?

If he switched a pair of wires, he'd have a hell of a lot more than an "occasional" misfire, LOL.

If they're all wrong, the engine won't even start. Ask me how I know, LOL.

Got any codes?

For some reason my truck won't show what codes are poping

joshua1998 · Jul 9, 2016

No all the wires are i n the correct spot

Check the number 8 or 7 spark plug and pull number 1 or 2 for comparison. If 7 or 8 are a lot more fouled than 1 or 2, compression test it. You changed the plenum gasket?

Ok, we at least you got the plenum out of the way. Short of doing a compression test on the cylinders, i'd be a little slow on figuring out where to go next.

You're saying that you do have a CEL, but can't pull the codes? Or there's no CEL at all?

If you did the plugs before the intake gaskets it may have fouled one. I would pull them and make sure they all look good

Double check wire routing. Crossing wires can lead to cross talk and misfires. Also what kind of plugs did you use?
