Rear driver side cylinder misfire. Does hit sometimes, usually stays working driving down hi way . Less likely to hit when stepping on it/heavy load. Changed wire and plug from my parts car but didn't matter. Do these have a separate fuel injector for each cyl? 3.1 v6
 
Separate injector system. Plugged injector comes to mind and replacement as a set is strongly recommended. Got a code?
 
It'll prably curse me but I might of cured it by just pouring a bottle of motor medic in the gas tank. So from what you said this is likely ah?
 
Techroline is an additive that you will find in a plastic jug, gray in color I believe, round base, with a cardboard sleeve around it.
About 6 or 8 inches tall and it tapers up to a neck that fits into the
gas tank to pour it in.
You can do a search on it to see what it looks like before you go looking.
If your engine starts running better, you might think about changing gas brand.
Maybe not Chevron, but something other than what your currently running.
