I am having a little trouble in the morning with warming the engine of
my '87 Westy (gas).
It starts fine and even revs a little higher (1300 RPM) then idle ~ like
some sort of choke action is taking place. The RPMs drop back down to
about 900 almost immediately (about 2 ~ 3 seconds of higher revs) If I
stick it in gear (automatic) and give it gas at this point, no go. The
engine doesn't accelerate at all - kinda acts like it is bogging down -
it will creep forward but not accelerate (this is the problem). After
about a small city block it begins to run perfectly for the rest of the
day unless the engine gets cold again. This happens everyday. Now if I
let it sit and warm-up for a couple minutes it will take off fine.
I know I should let warm up completely first etc. BUT I shouldn't have
to. Of greater concern to me is when it gets really cold outside (in
Colorado), I'm concerned that this problem will get worse.
I bought the Van about 3 months ago and it has always acted this way.
Other vans I have owned in the past did not.

Here is what I have seen to check from the archives:

Checked Temp sensor 1 with ohm meter - it reads in spec. The air flow
meter was just replaced about 3 months ago. Did all the ohm checks on it
and all seems in order.

Check temp sensor II. It to was in ohm spec. range.

Drained gas tank - Installed new fuel filter/fuel.

That's all I know to do.

Any suggestions that a do-it-youself'r-can do?

Thanks,
Al Ferguson
