What engine?

    Get a can of carb cleaner and spray the top of the engine especially around the intake runners. If the engine revs up when you spray it look for a vacuum leak where you are spraying. Also check the air intake hose between the MAF and the intake manifold for cracks in the folds or leaks.

You replace alot of things but you should replace the EGR valve and the throttle positioning valve also. I would start with the EGR valve

Since you have replaced all those parts already, I would suggest checking out the egr valve. Also I was wondering how the coilpacks or distributor are acting? Is the truck firing on all cylinders? Very possible you have leaky injector also.

I know that you did not mention any overheating but have the cooling system checked for hydrocarbons or do a compression test (all cyls should be within 20% of each other. Even if you had one completely dead cylinder, it is very difficult for wet fuel to get through an exhaust system without vaporizing. Your symtoms sound very much like a partially failed head gasket.
I could be wrong, but without the benefit of being there, that's what it sounds like.

Hello Charles...I don't know what engine package you have in your ranger the 3.0 or 4.0 litre, but regardless, a diagnostic scan needs to be performed to determine the cause of the problems. Sounds like the Electronic Engine Control (EEC-IV) has stored hard codes. A self test can be performed where Diagnostic Trouble Codes (DTCs) are transmitted on the Self Test Output (STO) wire located on the vehicle self test connector. The codes are in the form of timed pulses, and are read by the technician on a scan tool or the CHECK ENGINE light. With the information recieved the proper repairs needed to correct the problem can be determined, other wise you are just guessing.
Good Luck...i hope this helps and will fixya up.
