Problems started a few weeks ago. When accelerating car bogs down and slowly picks up speed.
From a stop it is good up to about 30 then the problem kicks in.
On the hi-way driving along is ok until the road goes up hill a little, speed slows down rpms jump up and down and car bucks.
If accelerating at this point it does nothing and sometimes will drop into neutral and tach out.
Also get random misfires every once in a while.
So far since the car has high miles I have replaced fuel filter, plugs, wires, coil packs, ignition control module and mass airflow sensor.
Also fuel pressure regulator had slow vacuum leak and was replaced.
What else is left to replace to try fixing this?
