I have an 89 ranger xlt ext. Cab with the 2.9, automAtic, and push button 4x4. starts right up but has a misfire that I just cannot figure out. Here's what has been done to the truck
-rebuilt motor and trans
-New injectors
-New plugs
-New wires
-New fuel rail
-new fuel pressure regulator( between 35-45)
-New MAP sensor
-New coil pack
- New fuel pump
-New fuel filter
-New exhaust for backpressure
- cap and rotor are good. Probably changing anyways.
- changing broken o2 sensor today
- no vacuum leaks
- and can't time because of misfire
And terrible on gas!!! Less than 10 mpg
If you've had troubles like this or have any other ideas that might do the trick please message me or text me. 734-717-9247. My name is Ryan and all ideas are welcome. Thanks.
UPDATE!!!!!!!!!
ive narrowed it down to a fuel issue...its getting way too much fuel and flooding the motor. that explains the random shutdowns while driving...but I don't know whats causing it. its got brand new injectors less than 2 weeks old. a new fuel pump. a new fuel pressure regulator. I don't know what else it could be other than the computer having a problem or maby that o2 sensor that I bought and haven't put in yet. any ideas please throw me any ideas and things to check.
