1995 ram van with v-6. when warm and cruising will start hesitation and
bucking to varying degrees, from slight to that of backfiring, no power,
worse on incline.The computor has been replaced, the fuel pump was replaced
with a carter unit several months ago.Was running fine for several months
after the fuel pump replacement (unrelated problem I believe) No engine
codes are set(checked with sophisticated Matco tester)Realtime info seems
ok.The fuel pump relay has recently been replaced also.Any educated guesses
on where to start?

Had the same problem a while back, or at least it sounds like what my 98 ram
1500 318 was doing. I had the injectors cleaned, and after that, I have been
ok.
At the same time, have you had the switch plate looked at?

Which switchplate are you referring to?
