So, there I was...driving home from work (early...)
About 5 miles from the office slowing for a red light, the truck darn near quit, but recovered at idle. 5 miles later as I was slowing for another light, the darn thing felt like it was going to explode! The engine was "surging" (or chattered, depends on you) between 500-1200 RPM, very rapidly, when I had the foot on the brake, and felt like it would die at any minute. I threw the trans into Neutral and held my foot on the gas, just to calm the idle down and keep it from dying in traffic.
A mile later, it started to run fine again...pulled into the driveway and it idled perfectly. Popped the hood and found nothing abnormal...let it idle for 5 minutes and never hiccupped.
Mind you, this IS NOT the first time this truck has done this, thus my original post. I was going to drive it up to South Dakota tomorrow, but will now be taking my wife's Expedition because I don't want to break down on the side of the road somewhere in Missouri or Iowa on the 1600 mile trip.
When I get back from my Xmas vacation, I'll be taking it to one of the most recommended diesel shops in Warner Robins, GA (Calhoun Auto). If they can't fix it, I'll be trading this thing in on something else...and I hope it ain't an F-150.
Any ideas as to what's causing this "surge" and rough idle? I'd bet an injector, but Ford says that everything is fine and it's NOT throwing any codes.
