Truck sputters at higher speeds

[flareside_thunder]

My next guess would be either the screen in the pressure regulator has some crap in it or it sounds like wnat my Buick was doin.......next guess is in tank fuel sock...replaced or not when you replaced the pump it could be sucking up some scale......you shut it off...loses suction, scale falls to bottom......etc etc. Tried to beep ya but your phone is off or something.

Need I say it???????

Update.

The tank was clean, as was the filter, so I gave up and took it to a Ford dealer. They found that the pcm was shorting out erratically and causing the problems. New pcm and the problem seems to be gone. (I hope)

how much do those run?

 

[surewhynot]

Mine was 168 and 210 in labor. With all the aggravation, I wish I would have taken it in sooner.

He paid $210 for someone to know what part to replace, and do it.

Diagnostics and installation. I gladly paid it. I would have saved money in time and parts if I would have taken it to Ford in the first place.

I stumbled on something weird. I knew that the coolant temp sensor was bad, since it was really just laying in pieces, so I went to autozone to get a new one. On the way there, the truck was running bad. I went to buy the sensor and they said there were two styles, so I went out and unplugged mine to see which it was. I plugged it back in after I knew which one to buy and wiggled it around a little. The truck started running fine.

I replaced the sensor and haven't been able to get it to sputter since. Could that have been the problem? I hate not knowing if it's fixed or not. I guess I'll hafta drive the piss out of it and see.

If the CTS wasnt readin the right temp the computer wont go from closed to open, and can make it run like that, the scanner should have showed the temp the sensor was reading, bet it was like -34 or something, we get that all the time with older hondas, and my gen protege 91 baby.
