erratic idle & hesitation in '95 4runner 22re

Hi-
I love my 95 4runner, but it's been a bit of a pain lately.
Last year I was experiencing some low idle problems and after an
adjustment and throttle body cleaning, the low idle disappeared but was
replaced by an erratic up & down idle whenever the AC was on. Jumped
from 500 to 1500rpm every few seconds.
It was only while the AC was on, which I rarely use, so I ignored it
(bad idea). Now the erratic idle happens intermittently, especially
when cold, with or without the AC. Also, soon after the erratic idle
reappeared, I've developed a hesitation in 5th gear when accelerating.
Do you think these things are related?

I've heard that this is not super-rare among these trucks. Any ideas
about what could be causing it?

Thanks in advance
Scott

A mis adjusted TPS will do exactly what you describe.

try to disconnect ur ignition cables one by one and reconnect them back
together, it might sound crazy but might work. I got that rpm jump once a
while with my v6 and is always one of the ignition cables getting loose for
some reason, just a thought, good luck
