Question about Ford Cars & Trucks
Changed throttle position sensor. Cranked up and idled good. Let idle for 20 minutes. Pulled on to highway and engine dropped to idle. Would not accelerate. Let sit cranked engine. Idled fine about five seconds. Wrench lights up idles very rough engine will not rev. Changed back to old sensor. Same result as new sensor. Worse off than when I started. ?????
Sounds like the catalytic converter or muffler maybe getting plugged up and the computer is putting the truck in limp home mode. Did you put a scanner on the truck. You might try to remove the 02 sensor ahead of the cat and see if it runs a little better it will not be perfect but should stay running if so do an exhaust check. When the cat or muffler gets plugged it puts back pressure on the engine and won't allow the fuel to be pulled into the engine properly.
