Road trip blues

[davidkerryedwards]

I thought about the solenoid last night. I wasn't looking at the exhaust when
it shut down
but one time the max fuel light was on when it happened. However, it put out
clouds of
grey smoke when I started it up each time, which seems to indicate there was a
lot of fuel
in the engine. I'll buy a coil of wire this morning to try this out should the
air filter not
solve it. It is certainly acting as if I turned the key off.
As far as the general issue of putting o ut a lot of black smoke with a plugged
air filter, I
think the theory is that since the engine is turbocharged, the sucking effect of
the turbo is
overcoming the plugged filter to some degree, pulling thru a decent amount of
air until its
power collapses a rubber hose section of the air delivery pipe. Lucky for me (I
think), the
shop where it now sits had another truck come thru there this spring with
precisely the
same problem caused by a small underhood exhaust leak sooting up the air filter.
