1997 Tacoma 2.7 4x4

I have a 1997 Toyota Tacoma 4x4 with the 2.7 ltr engine /w manual. It
has 160K on it and has started to miss from low rpm take offs. Once
over like 2100 rpms then it runs fine. It maily happens after the
engine has has hit a warm operating temperature. I haver heard of the
TPS being bad, but is there any way to check this before blowing 100
bucks on it? Can you unplug it and test it? What will this do? What
should it do?

Any help would be great.
Thanks

I just posted a similar message in alt.autos.toyota.trucks,

So far, suggestions from respondents are to check ignition wires and
fuel filter.

Your problem sounds a bit different than mine. Mine has either a 1-2
second loss of power (experieced that once or twice) or, more
frequently, a quick miss which is felt as a sudden jolt while driving.
Mine usually does it when cruising, light throttle.

The problem you describe is a bit like the stumble when accelerating
off idle that I had in my van. That was a cracked air intake hose
between the air flow meter and the throttle body creating a vacuum
leak. The crack widened when the motor moved on its mounts under
acceleration.

I'm not sure how the TPS works in these trucks. Some TPSs are a
simple switch, some are a rheostat.
