Hi Andy, It does not seem that your idle speed motor switch is defective. What happens is the arm is should have enough tension to keep the screw pressed down on the switch to engage it. One thing to speck is the spring tension on the throttle spool. I believe Rob Grady said there was a recall that you had to move the end of the spool spring (when you look at it you'll understand) one more notch to make it tighter, it could that it does not have enough tension to keep some preasure on the switch. If this is not the case or it seems to tight, then what you will have to do is remove the arm under the throttle spool that connects it to the air intake. Using caution to remove the clip first that holds it from popping off. Loosen the 8mm nut on it and screw the socket in one revolution. Clean the socket and ball end out, and lube it with the grease, then put it on the socket for a test fit. This should make it just a little bit tighter so it depresses the switch, if not try it one more revolution. When your finished tighen up the nut and re - insert the clip. To adjust you idle, loose the nuts on the 2 screw (that hit the switch), adjust the idle first (bottom screw) whil the switch is depressed, once that is done adjsut the top so it hits the switch and it engage, then one more turn for good luck ;) Should be set. - Shain #10140 --- In dmcnews@xxxx, Soma576@xxxx wrote: > Hey all, > > i'm having a problem having my idle speed switch engage every time i take my > foot off the gas. it seems like it won't kick down on it's own, i have to > hit the gas pedal hard and let it come down hard in order for the switch to > kick down to idle mode. > > first i tightened the cable from my pedal to the throttle, it was a little > bit loose, so now it is tight but not influencing throttle position. then i > unscrewed both idle stop screws on the idle hammer, and used a screw driver > to push in the idle speed switch as i set the car idle to about 900RPM (which > sounds good to my ears). then i screwed down the idle switch screw until it > was hitting the switch but allowing no more movement from the switch, but > being careful not to let it influence the idle speed screw below it. it's > still doing the same thing. > > how can i make my setup kick down all of the time? do i have a defective idle > speed switch? it won't kick down with you touch it with a screwdriver, it > only kick down if you HOLD the screwdriver down on it. as you let the > screwdriver up, the idle goes back up. doesn't seem right. > > any help? > Andy > > Soma576@xxxx > 1982 DeLorean DMC-12 VIN#11596 > Fargo, ND 58102 > > > [Non-text portions of this message have been removed]
