Engine/Transmission (1998.5 - 2002) De-Fueling? What & When does it occur?

[klaybus]

While pulling Snoqualmie Pass in Washington State yesterday I was running in OD @ 75+= MPH (No LOAD) & couldn't get above 2200 RPM's... . Was I "defueling" & that was why I couldn't get the RPM's up over 2200 & why did this occur? Any ideas?

Could be your fuel filter is plugged up.

Nope... Changed 2 weeks ago & was clean then... .

maybe due to the grade and the altitude you were using all the power that the engine could make and you simply could not accelerate anymore. i know that this happens to me occasionally. (not since the JVD ) being that you have a stock truck that would be where my money would go. i am not sure about the exact RPM but my 99 "feels" like it defuels around 2700 rpm or so.



just my observation.

We de-fuel at 3200 rpm and 115 mph

Klaybus,

Any chance your fuel was freezing... . you know gelling up in the lines. I have known that pass to be pretty cold sometimes.

De-Fueling

I don't think it could be "gelling". The pass temp is extremely warm this year (not a trace of snow) Hoping the dealer replaces the LP today & corrects the problem.

I will update this afternoon when I get my truck back.
