Idle problem again.

redmaro · 02-08-2007, 03:30 PM

I've changed the coolant temp sensor and it only dropped the Rpms to around 1000. Now I'm going to calibrate my TPS sensor, I have aleady taken out the whole throttle body. But I see that the throttle stop (The little screw bit) isnt in contact with the throttle lever (The springy bit that gets pulled when you press the accelerator). Should I move the stop screw untill it comes in contact with the throttle lever?

You didn't cover all the threads with teflon tape did you? Cover only the last half of the threads. If you cover them all, it will mess up the grounding of the sensor.

How long did you drive the car for it to idle to 1000 rpm?

Has the TPS ever been off the throttle body?

Are you sure you are looking at the throttle stop screw? There is another "stop" that is used for the dashpot and it's right next to the throttle stop screw and is easily confused.

I did put teflon on all the threads, I will take it out and do what you said.

Drove the car for a few miles.

Yes the TPS sensor has been off the car.

Let me take a picture.

Ok I had a feeling you did that.

What I do is, take a length of tape (about 2.5 inches long) and split it length wise in half, so you have a 2.5" long 1/4" wide piece instead of 1/2" wide.

This is the screw Im talking about.

Are they suppose to be touching?

Yes, it should be touching it. Since the throttle body is off, just look around while you move the linkage and see what is causing it not to touch the stop screw.
