Wes I have a problem with my 3.9L also. At 3000rpm it goes flat. It was just
tuned up with, I believe Champion RC12 plugs. That's what came out of it.
What does your 3.9 do after 2500/3000 revs?
Does it fall flat? (Won't accel any more?)
Just wondering if we have the same problem. Mine started after it was tuned
up last week.
