You really need to start making your own threads to be seen more.

The front bearings, I assume it is 4WD? If so they are sold as "unit" bearings, not serviceable, but the entire unit bolts into place.

hello
been awhile again

truck has not died yet!!

have a Q

my truck has a tendency to have a hard
time coming out of idle especially if the engine is cold
i press down on the accelerator and it just idles along with no power
then after a pause it will power up

this is something pretty new in the last couple of weeks

is there anything i can do about this?

thanks

dave

Just for future reference.... It's ok to start new threads when new problems arise. But if this works for you that's ok too. Just looks odd when a two year old thread pops up.

Anyway, it sounds like your exhaust back pressure valve might be sticking. Or maybe a dead spot in the throttle position sensor.

Well, welcome back! I agree with Scott, but if this is how you stay connected then, by all means...

In order for the PCM to respond to throttle input, don't forget these are "drive by wire", first the IVS(Idle Validation Switch) must be made, then the TPS(Throttle Position Sensor) or AP(Accelerator Pedal) using a potentiometer varies the resistance based on position.

Make sure when you start your truck that your foot is not resting on the pedal, if it is, and the IVS made then you will not have any pedal input until the IVS cycles again. You or anyone can test this theory by holding the pedal to the floor at startup and it will not rev above idle if properly working.

I would start by removing the pedal assembly and cleaning the IVS and TPS with electronics cleaner first. Personally I do it about yearly.

If your EBPV is sticking, it will sound like a jet engine out of the tailpipe, that's the easiest(or first) indication of a sticking EBPV.

the truck doesn't hesitate as much now
but for some reason in requiring long periods of cranking to start

then it makes a rumpff....rumpfff...etc. sound
then will smooth out

what could be causing this?

thanks

Sounds like the "Romps" are you running conventional or synthetic oil? Many have good luck running synthetic like Rotella T6 5W-40 to aid the issue.

sorry
i'm back to my original thread again
just can't let it die!!

think my 1st plan of attack
will be to remove the pedal assb as suggested above
and give it a good cleaning

do these parts come apart so one can do this?
what is the best way?

thanks for being so patient
dave

I don't think the 7.3 Bible link has worked in a long time. As for the hutch mod, here's some reading for ya.
