Hi Stu

Make sure that when you apply the 12 volts to the fast idle advance solenoid
that you tap on the gas pedal. Then see if the idle is higher. The idle is
then adjusted by turning the solenoid's plunger. Then take away the juice
and the idle should drop back to normal 650 rpm carb idle stop. The
solenoid is NOT designed to move up the linkage on its onw and kick up the
idle. You must hit the pedal after giving it the 12 volts. The solenoid is
only designed to hold the higher idle position until the voltage is removed.

Hi all!
I took the green wire off the top of the high idle solenoid. While engine
running, I jumpered 12v from one battery to where the green wire hooks up on

top. Nothing. No change and no high idle. Bad solenoid?? Where do you
get new one??

Hey Stu,

Sounds like the solidnoid that holds the idle up, which is on the top of the

IP, might be on its way out, or B, the sensor on the rear passnenger side of

the block is on its way out. Its at the very rear of the block, passenger
side, and it clicks off when it reaches a certain temp. Mine usually keeps
it on for 4-6 minutes depending on the temp. One way to see which one is
bad, unhook the green wire going to the solinoid, give 12 volts directly to
the solinoid, and see if it stays on for more than 30-60 seconds. Remember
to push the accelerator to the floor once its enrgized. The sensor can go
bad, had that happen on a m1008, it wouldn't keep the throttle up at all, or

the solinoid can get weak and go tits up.

Good luck.

Caleb
