Lets see if you guys can start throwing out some ideas here my father is getting stranded on his way from Texas to NY, 4th time he has had to stop now and its getting expensive, and frustrating to say the least.
2000 7.3 6spd with 250K miles. Truck ran flawlessly for the past 40k miles but now the passenger side cylinder bank is cutting or so we first thought. First day it started it was running bad like it was partially missing. Checked all of the Valve cover connections, tested pulling one VC plug, passenger side first, idled the same. Reconnected and then pulled the drivers side and truck wouldnt start at all. After calling a few people from the forum concluded that it was the IDM. Changed the IDM, still same issues. Took it to the Ford dealer and they did a buzz test and contribution test, and 3,5,7,8 came up "bad". The Dealer ended up throwing a bunch of parts at it, new Valve cover harnesses, and flushing fuel system. On the road he goes.
100 miles later the truck does the same thing running like crap, and they limp to a dealer. They check it this morning and #4 and #8 are failing. Tech said they were stuck open, didnt know whether it was mechanically or electrically. But anyways replaces them and they are on the road again, 300 miles later its happening all over again and he is stuck in a Autozone parking Lot in HOPE, AR.
He says it feels like the truck is running on 7 cylinders and he can barely maintain 50mph. Is there a scan tool he can buy to run a buzz test to see if the same injectors come back up?
Any thoughts guys/gals, I feel bad he is getting stranded like every 100-300 miles on a 1600mile trip home.
