Cliff Ruggles:
Next verify it is getting a full 12 volts.
Then verify that the heating element is getting hot
You will need to remove it for the last test.....
BanditRich:
What's happening with the choke is I start up the car & it's on high idle & stays there no matter how long I wait to put it in gear. When I had the Edelbrock carb on there with an electric choke once it got to normal running temp I would tap the gas and it would drop down to low idle.
That does not work with this Quadrajet. When I put it in reverse or drive it instantly drops to low idle.
And after I drive it and put it in park it goes right back up to high idle.
I checked for voltage and it has it. Maybe I need a new electric choke?
BanditRich:
I will be checking to see if the heating element heats up on Monday. I'll let you know if it is and you can advise me what to do after that.
Cliff Ruggles:
I test them on a 12 volt battery. Ground the backing plate on the ground post. Hook up a wire from the + post. It should start heating up immediately and within 1-2 minutes the metal coil spring should be hot enough in the center you can't keep your finger on it......
BanditRich:
Thanks for the instruction I'll let you know Monday after I test it.
