1991 Ford Ranger 4.0 XLT
204,000 KMS
Starts and idles fine when cold. Once I move in to drive it will switch intermittently between working normal and huge power loss/running rough like its on 3 cylinders. Eventually it will heat up the coil pack until it blows.
I've replaced the fuel pump, filter and pressure regulator. Had a diagnostic done, the fuel system is all working fine.
Replaced all the spark plugs/wires/coil pack.
I cleaned out the MAF sensor and initially it seemed to run better so I replaced it with another one. No change though so just a fluke i guess.
