Likely an early sign. I replaced mine at 46k and the bucking was bad under very light throttle. I'm nearing 68k and I feel like I'm starting to notice the early subtle symptoms again.
Man, I'm under 13k miles on the truck. I'll have to keep note of it next time it happens and report it to the shop.
After start up and in drive or reverse, the throttle response has slight to strong hesitation when depressed...like it's on or off making slow maneuvering difficult...at slow speeds from crawl to 40-50ish while holding with cruise control the throttle feels like its going on/off on/off causing a bucking sensation...
Nope...warmed up 100 miles or 10 miles...park run into gas station...restart...huge hesitation...I don't believe it's the hoses...it's the sensor failing...
Okay thanks, I understand that its the sensor. My understanding on the reason for the failure is moisture getting in to sensor from the exhaust gasses.
I think this is wear item...Ford should just put out a bulletin so owners are forewarned that it might happen at certain mileage...granted, some fail earlier than others so it's hard to predict when this needs to be done...with mine, this started to happen around 90K...right before my tranny exploded...
With all the electronic sensors and parameters in the truck - apart from lifespan issues in them for whatever reasons - does it make sense to clear the KAM on occasion - I can do this with my SCT box - and (I presume) force the throttle body to re-learn or re-calibrate itself? I wonder if Forscan is useful for stuff like this and if this or other driveability issues are lurking that aren't major mechanical issues?
Did you have problems before? If so, did this fix helped?
