truck dies....

[5.0Flareside]

ok guys.. im having an issue with the flareside..

its cutting out at cruising speeds sometimes and also will die when pulling up to a stop. also surges some at idle etc. will die at times in park idling..

not always but often after its warmed up.

i cant figure it out. thought i had it fixed with a idle adjustment but wrong..

IAC????

Pull the codes. See if the computer can at least give you a hint on air vs. fuel

ill have to check it tonight.. it wasnt throwing anything before trans other than Throttle position sensor.. already replaced..

Shot in the dark. Could be a ground issue, had serious issue when my bronco2 went in for repairs. They detached all sorts of wires to work on the transfer case. Had to go through the whole thing, but I fixed the problem but didn't know which wire was the culprit.

Trying cleaning the iac for you problem at idling. Also check for vacuum leaks. Check fuel pressure pressure at cruising speed and see if it drops or anything like that.

 

[5.0Flareside]

cleaned the IAC. reset computer...

nothing... same problem.. ill play with it tomorrow after work.. its a shame cause i was gonna be able to drive it today.. DAM IT!!!!!

I was thinking more along the lines of fuel pressure regulator, but you really need to know if it's air or fuel.

Need to drive it with fuel pressure gauge attached and monitor what is going on.

Chris I hope you get it figured out quickly

 

[73F100Shortbed]

I'm sure he will. He needs to get some more info and do some tests and then we will be able to help him with what to check next.

Chris I hope you get rid of it quickly

Damn Cliff, don't put any ideas in his head! LOL

I'm with Ryan....fpr or something in the EGR system. Also, make sure your TPS voltage is within spec.

The tps better be good. Changed it the day after I got the truck..

 

[flareside_thunder]

Eh, it could still be out of range. I don't know why Ford didn't use the adjustable TPS on the trucks like they did on the mustang.

 

[73F100Shortbed]

Eh, it could still be out of range.

Yeah can't hurt to test it just to be sure.

 

[5.0Flareside]

pulled codes hold on..

ill post em in a second..

 

[5.0Flareside]

21... cooling temerature sensor out of specs or ect out of range

23.... TP sensor out of range or Idle set to high (idle is mine had to to keep it running)

24..... Intake Air Charge temperature (ACT, IAT) sensor or vane air temp (VAT) sensor out of range.

34... Evap control system fault/voltage higher than closed limit/defective EGR pressure transducer sensor.

Remove neg batt cable to 15 minites and or clear codes n drive some more.

For all those random codes to come up i have a slight hunch the pcm is taking a poo poo on ya.

Also, are u sure everything is back in its original spot after the trans was installed? IMHO i would return it to the trans shop and let them know about it.

I can't drive it its so bad... but ill try.

Transfer shop already checked it again

I wouldn't jump right on the pcm being bad either. You need to test the sensors, etc. If one can't compensate for another being out of range sometimes you will get semmingly false codes. Also check the wiring for the sensors and make sure nothing is pinched, frayed, or bare. Since you said you already reset the computer with the same results doing it again probably won't help. Unless you did not have those codes the first time. Then it is worth a shot. Trace the wires back from those sensors and see if they are in the same harness and see if you have a common broken wire somewhere.
