Who all has had their throttle body replaced from a warrenty issue?

What were you're problems and were they resolved by replacing the throttle body.

I already replaced the TPS and that did nothing for me.

Thanks!

 

what exactly does ur truck do?

 

Alot of times when I start it, it instantly goes into fail-safe mode. When that happens, I have to plug in my XCAL and clear the check engine light to even drive it.

I just leave it plugged in 24/7 now because I have to use it so many times every day.

Also, it stalls out at stoplights alot. By alot, I mean just about every other light I go through. When it stalls, I have to reset the trouble code or it won't run. I have carved a path home from work that is FAR out of my way, but its mostly filled with right turns so I don't have to fully stop in traffic. :@

Other times, it drives itself. Literally. It gives itself throttle. I can take my foot off the gas and it will almost maintain a constant speed on it's own (NO, it's not cruise control). When it's doing that, and I come to a stoplight/sign, it will surge with ever downshift.

 

Nobody huh?

I'm gonna change the throttle body and fuel pressure sensor. Those seem like "logical" choices at this point.

Somebody buy my truck so I can just be done with it.

Im not kidding.

 

what are the codes coming up as?

 

Mine was replaced under warranty.
The idle was irratic to the point it would stall at stop signs and red lights, took it in to Ford service and they told me they couldn't find anything.
Then one day when i was driving at a low speed, the RPM's revved to 6K then back to below 1K before it stalled. When i tried to restart it the engine light came on and this time stayed on.
Took it back and they replaced it. (I have the 4.6) old style was a 2 piece, the new style they put on was a 1 piece unit.

 

Sounds very similar to my symptoms.

The only codes Im getting are Failsafe codes. p204 p2106 p2111 and nother pops up sometimes too... p2135

The only codes I get are ones that tell me the obvious. "I know you are in failsafe mode you damn truck! You don't have to spit a code at me to tell me that!"

 

I had my TB replaced on my '04 FX4 5.4l, luckily under warranty. I had a very low idle about 600rpms(almost dying out), and every time I tried to do a 3 point turn away from my house it would die out, for instance when stopping and shifting into reverse, dead??

Running the edge evo with a volant intake was my problem. They just don't work together. After replacing TB I have been only using my intake until Bill gets done with my custom tune. According to Bill the custom tune will make my intake and programmer work together instead of causing problems like drone and running lean.

 

SOunds like a plan! Thanks for the responses.

To me, it only seems logical that if it instanly goes into failsafe, it's either a fuel issue or a air control issue.

Maybe the fuel pressure is too low/high at start up and it trips it into failsafe or the thottle body isn't opening and it's flooding out of somthing.

Any other ideas?

Quinton... where are you?

 

what kind of tune are you running with the XCAL? Can you load a preloaded tune or your stock tune and see if there is a difference between the two?

 

The tune hasn't changed in over a year.

It's somthing electrical or mechanical that has failed.

I tried two different tuners and resorted back to the tune that came with my supercharger.

 

Don't clear the codes, that pinpoints the cause and can diagnose the problem. Without the codes, it's just a shot in the dark and you could pay for all kind of parts/labor for nothing. They are there for a reason and help the tech get it right. I worked on Mercedes and would be totally lost without the laptop and the codes it indicated. Sometimes a test drive would help me out, but clearing the codes is just stupid.

 

Did you not read a damn thing I wrote?

I get the same 4 codes every time. All 4 codes are basically the same thing.

I never stated I was gonna take it to a "tech". That's a waste of time.... and time=money.

When I reset the codes, it also resets the "service engine soon" light.... this way, I can actually drive it.

 

i replaced my throttle body because the truck was sometimes stalling at traffic lights. no codes ever. it has not stalled at all since.
