94 Buick Skylark hesitates when accelerating especially uphill
We have changed fuel filter, air filter, plugs,
coil packs, nothing helps. It has about 50k
miles, 4 cyl engine. Also seems to be
getting less gas mileage than normal.
Check for codes, you may have a sensor that is out of specs, you also might want to check the fuel pressure and flow rate too.
