I have a 96 Voyager with the 3.3.
Here's the problem i am having.
At speeds at around 110km and above the van seems to "buck" or "jerk" every now and then,some times just once,sometimes in set's of 2 or 3jerks.
I notice the rpm's go down for a split second when it happens.It can be fine for 2o km's or so inbetween episodes.
Any ideas?
Thanks in advance

 

does it only happen at or around that speed or does it happen at all however small while changing up through the gears?

have you changed the fuel filter recently (or at all) revs would go down if fuel is either restricted or maybe air creeping in somewhere?

had similar issues with an old peugeot I had, it was a dodgy clip clamping the hose on to the injector pump and it was sucking in a tiny air bubble now and again!

was a head scratcher for a while

hope this helps

 

Thanks for the reply!
It only does this at Hwy speeds,i am begining to think fuel pump.
I wish I could describe it better,but like I say,it's just a jerk every now and then while im crusing at a around 110 km or a little higher.it doesnt do this while I am driving around town.Everything else seems normal.
