1989 Plymouth Sundance When you Press the gas its jerking I replaced the fuel filter but still the same problem What else can it be?
I'm having the very same problem with mine and have been told
it's the catalytic converter that needs to be replaced. Apparently
it becomes clogged and the oxygen can't flow through properly. I
hope this will at least give you a lead of some sort. Another thing
that was mentioned that I am looking into now is a 'map' sensor????
