1994 Buick Park Avenue Q&A
1994 Buick Park Avenue Question: Engine is still bogging when hitting 40 to 50 miles on gradual up hill driving.
Wasn't doing this before I did tune up, added new fuel pump, adv valve was changed, exhaust hole patched, supercharger oil drained 2x, new battery, changed starter, serpentine belts and so on. Car used to go hill and pick up speed easily, now it's bogging on just a slight inclination when speed is accelerated between 40 & 50 mph. - [deleted]
Have you changed the fuel filter, then I would check fuel pressure and volume of delivery, then check un-regulated pressure. May have restricted exhaust/catalytic converter.
