While driveing, the van seems to hesitate during acceleration and at times feels like a misfire the misfiring is random and feel the hesitation at signal lights and after the van has been running for a period of time.
I have replaced the fuel pump thinking it was a fuel delivery issue, not that. Should i change the fuel filter next?
You should definitely replace the fuel filter though this probably won't fix your hesitation. It wouldn't hurt to replace the spark plugs this is usually the culprit on these engine. I have the same engine in a '99 caravan and found the for some reason the spark plugs on cylinder 3 and 4 loosen up after one year and cause a misfire between 45 and 50 mph under load (when mildly accelerating).
