Working on a 1974 2.0 d-jet
-symptom 1- when i start it... idle is very low no where near the 1600 rpm as Brad mentions -symptom 2- low idle...like 550 rpm -symptom 3- when coming to a stop it almost dies -symptom 4- stomp on gas when sitting and driving it goes blah... then takes off. -symptom 5- as it warms up loses a little power things to note: -there are 20 clicks when pushing down accelerator so tps is correct -timing and dwell were checked today and they were within spec. -lifters just adjusted |

Some one else had a similar problem in the past. Seems the AAR was stuck in the closed position. In the past it may have been sticking slightly in the open position when hot and causing a high idle, so the throttle adjust screw was adjusted to compensate. Since it is sticking in the closed position( maybe) now, the idle is too low. I would check out your AAR and see what condition it is in. Pretty simple to remove and clean and test. Easy to test on the car also. When you first start the car, remove the hose from the AAR that goes to the air cleaner - plug the end with your finger. Does the idle go down? Yes - AAR is open and should close after 3-5 min. Test again after 5 min. Is AAR closed? Idle should not change. If the AAR doesn't work like this, something is causing it to stick. Or it may be burned out. I had to replace the wire on mine as it was burned.
