I'm under the car and pulled the plugs. Tried the reading directly at the thermistor.
I checked the thermistor when the engine is cold. I do not get any reading with the ohm meter. I believe it needs replaced and possibly this has been my problem. Your thoughts?
I have done everything suggested and the car still idles at 1,500 RPMs when hot (not cold - 775 RPM) and in park/neutral. So a few more questions......
1) Does the ECU control the idle RPMs when...
I have. Here is a photo of mine. Do they look bad?

I started the car in Park. Pulled the plug on the Thermo Time Switch. Jumpered the Microswitch. The Curb Idler Screw is not touching. The Butterflys are completely closed (I removed the U-Pipe...
Spent today checking everything again. First, did the throttle adjustment like suggested above (lots of detail!). Long story short the microswitch is bad. When the engine is idling ONLY, I jumper...
Now I'm thinking that there is not an air leak. But with the throttle completely closed and high RPMs, there has to be fuel coming from the Cold Start Valve (CSV). I will check this tomorrow by...
Well now I did it. After messing with a bunch of things, here is what it does now. When in drive, lights on, A/C on or both off, it idles nicely at the 775 RPMs. However, now when in Park it idles...
Messing around trying to figure out the idle changing issue. I looked at the deacceleration springs and they look OK. I juggled the copper tube (tube of agony) from the ISM to the intake manifold. ...
Well, I thought I had the idle issue solved. I don't completely. Sorry, but here is a list of questions to help me understand.
1. I thought the ECU ALWAYS controlled the RPMs at 775. If so,...
Easy enough! Problem is even though the hinge bolts were a bit lose, it didn't completely solve the intermittent rattle sound. I'll keep investigating. Thanks for the instructions!
The engine cover is making a rattling noise on the passenger side. It appears it is the hinge end NOT inside the engine bay. How do you get to the other end of the hinge? I guess you need to...
All vacuum hose were replaced. And as I understand it the original ECU sets/controls the 775 RPM. I set the idle screw a bit higher but not much.
Just to finish up what I did and was asking, on my Dwell Meter I adjusted the fuel to air ratio when the engine was hot, the "computer" was swinging the meter needle back and forth. I adjusted it...
Found it! It was tucked back down behind the engine. The plug is connected to something that continues down behind the engine.
My problem is I cannot find the plug or orange wire. Any pictures or more specific directions where it is? I'm sure it is right in front of me like thinks in the refrigerator. lol.
Since I just replaced the Fuel Injectors and Idle Speed Motor, I thought it might be a good idea to check/adjust the air to fuel ratio. I have read some of the threads and watched a video and on my...
So, I was going to run a jumper wire between the two interior courtesy lights to test for a bad hard wire. That's when I noticed both light wiring connections (purple, purple/white, black wires)...
Checked the 3 diodes. All checked out at 0.55X. I narrowed down the issue which is only with the front and back courtesy lights in the door open/close position to turn on and off. In this position...
The idle speed motor was bad and I did replace it from one from Deloreango.com. That did the trick. Car starts right away at high idle and drops down after just a little. I still think I may have...
I replaced all the injectors after it appeared some were bad. I let the car sit for a few days to see if that helped. It did. Engine fired up right off. It looks like the original leaky injectors...
I am trying to get everything working including courtesy lights. The one in the engine compartment no longer work but it did before. It has no voltage to it. Also, the two courtesy lights in the...
Does anybody know physically where the electrical connection is as circled on the attached partial wiring diagram? I'm guessing it is under the "T" top panel? Is there anything that shows the...
After all the excellent advice from everybody (and greatly appreciated) on what to look for and reading other threads, here is what I did and found. The microswitch does engage when the throttle is...
