Hesitating
I have a 1988 Ex-WSP SSP......I have over 210,000 miles on it. I just had the Fuels injectors replaced, a new fuel regulator, Changed the Intake AirCharge Sensor(It was Very nasty looking), and Cap & Rotor.
When I try to accelerate it still hesitates. It's worse going up hill. There is more power than there has been, but the hesitating is driving me nuts!...If I light foot the gas pedal it does fine except up hill. Any Help?... |

Also check your exhaust system. You may have a blocked or damaged cat(s).

Did you change the fuel filter ?? Might be clogged up if it hasn't been changed regularly....

Fuel Fliter has been replaced, and is chaged twice a year.

check how the plug wires are placed on dist cap , lots of people don't know the HO firing order is like a 351w not a regular 302..
do you have a check eng light on ?? if this stuff checks out good , unplug 1 inj at a time , kinda like a power balance test . your bad cyl will show no rpm drop when you do the inj test . let us know your findings . ssp91ssp hector |

I clocked the plugs wires on the cap to the correct the 5.0 clocking. It has brand new Motorsport 19LBS Injectors, and Fuel Regulator.
There is no check Engine light. It just surges/hesitates under somewhat hard acceleration, and up hills. a light foot on the pedal it is fine. |
