Crankshaft Cog good, but not tight - replace?

[fixkick]

no problem!
the tps, is set to the idle switch just closes,
that is all there is to it, but the silly 16v put this (see photos below) in the way, I just remove the bracket

if the blower works on high always and not lower the blower resistor block is bad, behind the glove box, on the blower, box housing


TPS on the bench (a cake walk here)

on car.
set the feeler to 0.026" .65mm
turn TPS, until idle switch. pins 1, (bottom) and #2 next higher, pin, is below 500 ohms.
its a carbon switch that never goes to 0 ohms like real switches.

now the hard part.
this bracket is in the way,

the idle switch read infinity for most of its travel from WOT
down to hear idle, then suddenly drops below 1000ohm the lower, and 50 is lowest on most,
just get it hear 500, ohms,,, about,
i shoot from 300 to 500 ohm target here,
then lock down the TPS tiny side screws.

when the switch closes, idle controls on ONLINE, ISC comes on line, and holds hot idle a 800.

cheers to you and happy kicking, up there.!
