94 Explorer engine bogging
I have a 94 ford explorer with a 4L engine.
The vehicle has no acceleration and after it gets warm it won't go over about 20 miles per hour.
Upon trying to accelerate, it just bogs and looses rpms, won't rev over 2000.
Vehicle is running smooth at idle.
I have replaced DPFE sensor which took care of the EGR codes.
I replaced the Mass Air Flow Sensor.
No codes are showing up.
We tried new wires and it did not make a difference.
The spark plugs are 6 months old.
Went to check timing but can get no timing signal on the whole left side of the distributor.
The three cylinders on left bank will not trigger the timing light but all of them are giving a spark because I pulled the plugs and I got a spark on the plug.
4, 5, and 6 trigger the timing light but 1, 2, and 3 do not.
I have vacuum but did not check it with a gauge.
Any ideas???
Thanks,
Henry

Have you reset and pulled the codes since replacing the DPFE? Also, before it gets warmed up, does it run properly? When you start having the problem, so it idle OK? Sorry for the questions, just need some more info.

I disconnected the battery last night and took it for a drive this morning.
I am getting fault 186 now.
It is "fault in injector pulse width circuit high"
Does anyone know what to do with this fault?
It is still running the same.
