OK, I have been having the high idle problem for months now, replacing
nearly everything related to the TBI system. Thanx to everyone for their
Yesterday the idler pulley crapped out while I was hooking up my trailer
and it overheated(temp gauge was pegged well over the 260 on the gauge).
Nothing I could do to cool it off so I just shut it off. After a couple
errands in our other vehicle, I went and got a new idler($17.40 or so),
removed the old(plastic) and installed the new(stamped steel), the belt was
good so I reused it(though routing was interesting with no diagram(third
time was a charm)). Only lost about a quart and a half of coolant.
Started it up(same as before, needed the throttle cracked), let it run a
bit, then drove it home...
NOW, THIS is where it gets interesting... Pulled up in front of my house and
something was different...it was idling at 700RPM! Switched it to an AC
setting and it went to about 850-900RPM! Went out this morning to start some
running and it started first try with no throttle, went to 1000RPM then
1100RPM, then down to 700RPM after it warmed up! Started and shut off 4-5
times with no starting or idle problems(went to 8-900 and dropped right down
WHAT THE F%&#????
Any ideas on this new tidbit, anyone? Everyone?
