I found the choke cap (aka choke heater) on my '85 GT to be inoperative. I have the proper 7.2 volts going to the connector, but the choke will never cut back from the initial 2000 rpm fast idle to the interim 1200 rpm without me blipping the throttle. The coil never gradually opens the choke plate. It will then never go down to regular idle unless I push the fast idle cam manually out of the way. The choke plate never fully opens and blipping the throttle will return to the interim 1200 rpm since the fast idle cam never gets the signal to release. The cap fails the resistance test and there is some corrosion inside. Basically the cap/heater/coil does nothing. I would like to have an automatic choke on the car (desired but not required), so I see three options:
1) Run with no choke. I've done this before and for a seasonal car is probably okay.
2) Replace the cap with an OEM unit that uses 7.2 volts. I can't seem to find one of these.
3) Replace the cap with one that uses 12 volts and is adjustable. If I opt for this I need to identify a 12v source that is only hot with the engine running. Anyone know where one is?
Is the OEM 7.2v choke cap available anywhere?
Thanks for reading.
