Hello all… I was just wondering if this sounds right with you guys, when I override the ISC motor (ps03 – warmer button) to extend its arm, it takes about 5 sec to extend it all the way out and with click click click noise. But If I command it to retract it’s self, from the extend point, it will take about 2 min to retract it’s self all the way down. Also when it does there is a steady click, click, click noise.

I'm thinking of replacing it but I want to get the members' blessing first.

So there is 2 concerns; :confused:

1- the time difference from extending the plunger and retracting the plunger

2- the click click click noise. Again only happens when it retracts.


THANKS!!!!!:thumbsup:

It certainly sounds like the ISC motor is failing. It shouldn't click like that when retracting and it should retract fairly quickly not take 2 minutes.


When you install the new one retract it fully and make sure that there is about a .030 gap between the ISC plunger and the throttle lever with the throttle completely closed. Turn the plunger to adjust the gap.

That is what I thought, thanks for the reply, I'm going to search around for a new one. Funny thing is, the car drives fine and it idle fine too. But the clicking noise, is bugging me. thanks for the help..... again.

Here is the tool I made to adjust ISC motor's plunger easily.

How much did that cost you? LOL! :)

I know only the exact cost of parts! lol

Hey HUF and CaddyDaddy,
So do you guys think I should change the motor???

Yes, it is bad. It should move much faster in both directions, and should not make clicking noises at all. Besides, I believe it makes pretty loud ratcheting noises when you shut the engine down.

Always follow Chevelle's advice. I cannot recall any case he would be wrong.

Yeah, it sounds like it's taking way to long to retract. Mine doesn't take 2 minutes!
