Hello, having problems with my grandfathers 94 ranger with the 4.0 v6. When your trying to accelerate around 1/4 to 3/4 throttle it hesitates real bad like it has no power. If you take of easy like under 1/4 throttle it seems to be ok. Also, if its hesitating and you go over 3/4 throttle it picks up power all the sudden takes off like its fine. I tried cleaning the MAF sensor (didnt seem dirty at all but tried it anyway) and the fuel filter has also recently been changed. I was starting to think maybe the TPS sensor, but im not sure. Any help would be great. Thanks.
 
Almost sounds like the TPS or an EGR...they have a tendancy to do that. Also like holligan said, try doing a tuneup with wires, plugs (autolite double platinums) and a pcv valve
 
Can you get a used one fron a yard? I went through the same thing, dumped a thousand dollars trouble shooting it and it was a bad coil pack. Try a used one see if that will correct it
 
Well I changed the coil and still does the same thing. Just feels like it has no power between 1/4 and 3/4 throttle. Seems to do it worse when its cold or after you first start it up.

Yeah they were changed like 6k ago. Problem seems to be worse when cold. After it warmed up it ran good. Then i shut it off, went into the parts store, came out started it back up and it ran like **** the whole when home even warmed up.
 
Also, it does pop a CEL on every once in a while. Is there a way to check to code with a scan tool? My grandfather said the light would come on and off before it had the problem but I would still like to check it to make sure.
 
I'd check fuel pump pressure.
there is a way to check the code with and without a scantool. you'd need an analog volt meter.
