It does it sort of all the time. Sometimes more than others. Haven't noticed a pattern or anything yet though. Anything I should check for or look at?

 

Could be just about anything then, from tune up parts, to sticky injector.

 

Recommended action? I know the plugs only have about 1k mi on them, the cap, rotor and wires have about 20k mi on them, oil filter, oil, and air filter changed about 1k mi along with plugs. Plenum was done about 300mi ago also

 

Might try running some seafoam thru it first, both in the tank, and thru the vacuum line for the brake booster. Clean things up a bit.

 

I'll do that this weekend, and report my findings

 

Okay guys, I'm putting on my adjustable track bar tomorrow, and then I'm doing the seafoam. I have a question though... I've seen people say to put 1/2 the bottle in your brake booster vacuum hose and 1/2 in the gas tank. I have also heard people say to do 1/3 in the vacuum line, 1/3 in your gas tank, and 1/3 in your oil??? Which is right?? Also, has anyone on here used seafoam on our trucks? How did it go?

 

None in the oil. Bad idea.

I put a can down the brake booster line, and some more in the gas tank. Was a very smoky experience.

 

Same here..

 

I put a 1/3 in the BB and no smoke so put the rest in the fuel tank. Like HY said not in oil. Thins it out does bad stuff..don't let her stall

 

Well I didn't get around to the seafoam last weekend. gonna do it this Sunday. Anything I should/have to do before or after the seafoam?
