Hi guys ,
I just hope that someone could help us with the idle of my '75 2.0. I have the car for almost 7 years now and idle was always a little bit too high. We have been trying to correct this but it got worse instead of better. We changed the distributor to a 123 ignition, we changed all the vacuumlines, the AAR has been cleaned out and the idle screw is completely closed. The car starts at 1600rpm when cold and once it is warm it goes to 3000rpm and the idle stays there. The car pulls very well , a lot better better than when I just had it.

test the AAR after the car has completely warmed (and is hitting 3000 rpm) by squeezing the hose tight to close the hose. revs will drop if its a stuck open AAR.
you say you cleaned it. does not mean its working. a little bit of difference between AAR on a D Jet and an L. i have an L so someone else who knows would tell you how to properly test a D Jet AAR. does sound a little bit like the AAR is stuck open and is not closing. trouble shoot it to tick it off. good luck. other thing might be decel valve needing adjustment. idle vacuum is able to pull it open if its spring pressure has become weak. this is something that has come up on L jets - not sure about D Jets. adjust it via the nut on one of the hose nipples. |
