Engine/Transmission (1998.5 - 2002) intermittent dead pedal

[sgoeing]

I was towing about 6k the other day and lost power. The engine was still running, but it would only pull about 2-3psi and pressing the pedal didn't help. I would let off, and then hit the gas, and it would pull up to 15 or 20 psi again. Sometimes it would hold for a minute, sometimes not, and then if it did hold, it would eventually drop power again. I had no errors.



Any thoughts? I really need to address this. It was pretty disconcerting wondering how I was going to get a 5k lb truck and a 6k lb trailer back to the house from 100 miles away.



This is my 99 auto. The only mods are FASS and EDGE juice with attitude.

Check for codes... . I bet your APPS sensor needs calibrated or the contacts cleaned. My truck did the same thing & no codes were present until it died completely. TDR mag issue 54 page 20 explains how to clean the APPS.

my bet is its the vp-44. get some auto supply or shop that has a scanner. if you get a 0216 its the injection pump.

Can I get a cheap code scanner somewhere?

Yeah... that was in the back of my head to, but I try to think positive.

Advanced Auto does free code scans.

I tried that before, but they had issues getting mine scanned and cleared. I wonder if there's an issue with the Juice?

It was my main thought, but I was trying to think positive as well. Like maybe it was a clogged up fuel filter, bad sensor, etc.

Is this procedure posted somewhere online? My TDR mag is missing.



Thanks

Do a search on APPS... . lots of info.

Yes, I've seen millions of threads about resetting and calibrating the APPS but never a thread about cleaning it. I'll search around.
