hi my name is evan and my 2004 explorer 4.0 vin k with fly by wire system. it has a delay in acceleration when the gas pedal is pressed to get the truck moving. i slowly push the pedal down and the truck goes nowhere then it all of a sudden decides lunges forward. it feels like when you pop the clutch in a 5 speed.

Is your CEL on at all?

Is your CEL on at all?

what is the CEL

 

[DirtyDog]

CEL=Check Engine Light. On your Explorer it will say "Service Engine Soon"

 

[Donner]

Does this occur in Reverse or any other gear?

Tranny fluid may be low.

the cel is not on. it came on once when the tranny made a shutter feeling 2x. so i checked it so there was a pending p2106 code saying the TPS had some kinda malfunction. it reset itself after the key was turned off and not stored at all. brought it to ford and it wasnt there and they had explaination to the problem. tranny has been serviced 2x tranny and it is full. it does do it in reverse as well

i also did replace the tps after the dealer recalibrated the pcm

2004 explorer suv 4.0 79,000 mile acceleration hesitation

ive been reading alot of other forums and stuff and alot of people were saying the throttle body needs replacing. they have the same symptoms. and some were saying to clean the tb,maf and anything else attached to the intake. and since the pcm was recalibrated before i installed the new tps which is not ford part it is a BWD part. do i need to recalibrate the pcm again or should it be fine. i was reading a ford post on a problem with the eplorers haveing a p2106 and a p2135 code together and they say to replace the tps THEN recalibrate the pcm. do they do that to get the newest calibration in or the match the sensor to the pcm
