Maybe.. But wouldn't injectors also give me problems while my foot is on the gas driving?

Something else I noticed... If the AC or Heat is on, the truck runs fine.. no more studdering.

Is there an easy way to check for Vac leaks?

Also is there a diagram somewhere of all the vac lines? I'll check my haynes manual.. havent seen anything in there for that but I wasnt specifically looking for it either.

Under the hood on the hood should be a diagram. Also Chiltons manual.
