The idle on my 83 CJ7 258 became rougher and rougher over the last few months to the point I cold not drive it. I replaced the Carter BBD carb with a rebuilt and the jeep ran wonderfully for 24 hours. Today the same old rough idle is back and I barely got it home. I've rechecked the timing, vaccum lines, and connections. The idle mixture screws are out so far they look like they'll fall out of the carb base. When I try to turn them in to an acceptable setting the engine stalls. Then, magically, the engine idles perfectly. I re-adjust the idle speed and idle jets and I jump in and test drive it and it'll run okay for a mile or 2, then we're back to undriveable. It seems to be in a control module or something. There will be a very slight click behind the carb (like a relay or solenoid click) and the idle and engine become rough and eventually stalls. Someone please help. I've disconnected all the vaccum hoses and plugged them off with no improvement. Any ideas?

Re: Re: rough idle
if like me and dont have $300 to throw at your jeep at a whim then try this. it is a hella lot cheaper then buying a new carb to replace the rebuilt one you just bought and will prolly fix your problem if you can do it.
