Hi. Can anyone confirm if I'm on the right track or if I should be looking elsewhere for a fast idle cam on a Holley 750 w/ electric choke that is sticking? I took the Olds out for a ride today for gas and then to burn some. Initial warm up and drive to gas station was fine, leaving station was also good but then noticed the RPM's a little higher than normal. I pulled over to check it and the fast idle cam was sticking with each blip of the throttle. I could then manually push the cam down and it would stay until the throttle was blipped again. I took it back home to look at it further. I did not see any obvious binding in the cam or the rods. I then checked the voltage with a multimeter and wasn't getting much of a reading. I checked the voltage right at the oil pressure switch that the choke is getting power from and the prong reads between 2.5 and 6 volts. I doubled checked the meter against the battery and the alternator to make sure it was reading accurately.

Does it sound like the oil pressure switch is faulty and that is causing the choke to not operate properly?

 

The choke needs battery voltage to operate correctly, your voltage reading is low. Check the feed wire to the oil pressure switch, it should read the same as the voltage to the rest of the car.
