Is my carburetor the problem?

Asked by Mar 25, 2014 at 05:08 PM about the 1985 Pontiac Bonneville Brougham

Question type: Maintenance & Repair

I have a 1985 Pontiac Bonneville Brougham with the chevy 305 ci. 5L and Q-jet 4 barrel
carb. It idles between 1800 and 2000 rpm, it does idle a little rough when it does this.
This high idle causes it to keep pushing the rear whells making it hard to stop/go
smoothly, and makes it dangerous on slippery surfaces. It sometimes idles down upon
start up, but returns to high idle when driving. Fuel additives, carb cleaner and daily
driving have not helped. What is wrong?

Your choke linkage might be hanging up or re-engaging. There is linkage that steps up the throttle when the choke is engaged. Make sure all of the throttle linkage is free and not bound up.

and don't forget to check for a vacuum leak introducing itself at times
