o_rod Posted July 22, 2017 Share Posted July 22, 2017 Hey guys, Experiencing something new lately on my monte. As I'm cruising at light or part throttle and I let off the gas, the car will continue at that cruising rpm or it'll idle higher than normal. The only way to get it back down is by blipping the throttle, sometimes twice... My cable is not binding and works fine and my return springs seem to be doing there job, It's an edelbrock performer 1407 caburator as well. What gives?

Leghome Posted July 22, 2017 Share Posted July 22, 2017 I have an Eldebrock 1406 and sometimes it is doing the same thing. I have not found the reason as of yet. Quote Link to comment Share on other sites More sharing options...
Mo's70MCs Posted July 22, 2017 Share Posted July 22, 2017 Choke and fast iddle cam issues would be my first choice. Specially if blipping the throttle corrects it, it's usually how the fast iddle cam is unloaded. Quote Link to comment Share on other sites More sharing options...
o_rod Posted July 22, 2017 Author Share Posted July 22, 2017 Interesting... I no longer have a choke on this carb, I removed it and sealed the shaft holes. It ran fine like this until recently. Still learning carbs, but I'll research the fast idle cam, thanks Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted July 22, 2017 Share Posted July 22, 2017 if it's not the fast idle cam, the throttle plates might be hanging up, could be carbon build up, the carb warped, shaft bushings worn, or the plates moved on the shaft Quote Link to comment Share on other sites More sharing options...
cny first gen 71 Posted July 24, 2017 Share Posted July 24, 2017 My brother had a problem with his eldebrock was due to carbon build up, they say it is from ethanol fuel. Quote Link to comment Share on other sites More sharing options...
o_rod Posted July 26, 2017 Author Share Posted July 26, 2017 Seems my distributors vac canister was causing a nice vac leak. Removed it, readjusted timing/idle and seems nicer. Hopefully it stops raining soon so I can take it out and see if it fixed it. It also seems that I removed the high idle cam when I removed the choke so no issues there lol Quote Link to comment Share on other sites More sharing options...
