Julia's Problem

[jwasnewski]

I got a gut feel:
I am not the guru, no one wants to be wrong, and I do not care to
increase the stress level of the folks in distress.. I've been wrong
before but feel I need to try help these folks solve their problem.

I do not believe the air filter is the root problem!

Some questions: Applying the air in air out theory, if the air filter
was plugged how did Ms. Julia get from Gainsville, TX to Van Horn,
eveything working as advertised? Some 500 miles. The air filter was
ok in OK! Somehow in an instant it is plugged? Was there a sand
storm? If I have it correct the problem has been intermittant from
Iowa.

I do not believe that park dust theory either! That engine ain't
running when you are parked having cocktails. Just makes you wash the
bus.

How would a faulty air filter cause code 21 on the Allison
transmission? Something does not fit here.

This is what I would do!!

I think I would take a serious look at the throttle system and how it
interfaces with the transmission. I know absolutely nothing about
the throttle system but would bet it works off of a Potentiometer
somehow,(a fly by wire kinda thing) and something could be going
haywire there.

I'm not the sharpest tool in the box but somethin' ain't right here.
I think I would be asking lots of questions before I hit the road
again.
