I have a 77 with 2.7 CIS
I am havving an issue with a high idle that I can not bring down.
When I start the car (cold) my idle is about 3000. I can NOT bring this idle down.
- I unhooked the linkage so I know that the linkage is not causing it
- the idle stop screw (probably wrong name) is all the way in so it is not pushing the linkage up
- the idle adjustment screw is all the way clockwise, so I can not slow it down any more
The car starts great and idles smooth, just real high.
I have not taken it for a good run to bring it up to operating temps, I know this will probably bring the idle down a bit, but 3000 seems real high, even for a cold engine.
I did a quick check for vacuum leaks with carb cleaner but did not find any.
Another thing I noticed was that I can "turn" the distributor cap about 1/4" . I find it weird that there is free play with the distributor cap. I think the cap should be firm and not be able to change so freely. I changed cap and same thing with both caps. I did not "turn" the cap when the car was running. Scared to cause either a problem with the car, or SHOCK me
)
Any ideas? Or is this normal idle speed for a cold engine and I should take it for a ride and get it to operating temps then check RPMs.
Thanks in advance
