Anyone have a Ford 302 Econoline Van that jerked when going down the road.. I can't tell if it's an electrical or a transmission problem for sure... It happens fast, it jerks the whole truck like the transmission is letting go then catching hard.
I just put a new distributor cap and rotor in it tonight, it seems like it helped maybe a little bit but it still does it when accelerating or when in top gear cruising along at 55mph in overdrive ...when I go 70 it doesn't seem to do it.
This week end I'm going to put new wires on and change plugs but I'm thinking because of the severe jerk it has to be a bad ignition module, hall effect switch or tyranny.
I would be appreciate any opinions and guesses, thanks.
