My truck is running fine now. I changed the plugs, replaced the rotten intake couplings, and upgraded my coil packs to a set from Accel. Funny thing is my plugs have never been changed, not in 150K miles! They're original to my truck .... the gap on the plugs were damn near .085 lol. She's all better now.

Holy smokes dude!!! That is near twice the acceptable gap! Bet your truck feels powerful again.

Im running a set of NGK v power nickel plugs currently. Seems that the NGK laser iridiums didn't last past 50k miles. I've changed my plugs twice since owning my truck. I'm at 105k miles now
