I have searched and searched looking for an answer, but I haven't found a problem exactly like mine.
Backstory, I have a 2001 F250 with a little more than 100k on the engine. The number 2 injector went out a few weeks ago. I took it to ford to have it fixed.
Problem: A few days after the repair, I was driving the truck and noticed the throttle response wasn't there- it was driving fine, but all of the sudden it felt like it stopped getting fuel. Then after about a 1/2 second, it picked right back up and was fine.
I drive another mile or so, and I am coasting to a stop sign, and it shuts down. When I stop, I restart it, and it runs just fine back home. It didn't give me a problem for another week or so, (probably 80 miles or so) and it did it again but didn't shut down.
It was again fine for another week (200 miles or so) and Thursday it did it again, very slight and only one time on a 120 mile trip.
It has never thrown a code- or at least the Check Engine Light hasn't lit up.
Also, since getting it back from Ford, my EGTs seem high when climbing hills. They can easily get up to 1100, probably 1200 but I let out when it gets close to 1100. I'm not sure if this could be related?
The sputtering has never happened when I was accelerating, just cruising, or coasting.
Thanks for the help, and if permitted, I will stick around
Update: It was definitely the CPS. I picked one up for $27, grabbed a 10mm wrench and went to work. The one bolt was VERY tight. I was scared I may break it. It worked fine. 500 miles later and not a hiccup. Thanks
