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.

Throttle body is likely worn to some degree (they all are by now if they haven't been repaired), but I would still do as Zach and Phil suggested and do a smoke test.
Also, if you haven't already, remove and plug all of the vacuum hoses except for the one going to the MPS. If the idle drops significantly, add them back one at a time until the problem returns. If the idle doesn't drop significantly, the problem lies elsewhere- like the intake runner gaskets or a cracked plenum. |
