Ok. New O2 sensor, remaned carb, Idle is set at 600 RPM's. I'm still getting a CE light with a "Rich Code." The car still idles too high and if you start it warm the idle is too low and it stalls within 3 seconds of starting. I'm guessing the carb is just bad. For some reason it just says "**** the setting, I'll run rich if I want to dammit." I'm getting another remanned carb for free and trying this again. Can anyone tell me why my carb is deciding to run rich?

Try getting hold of Apeman on this sight. He seems to know what he's talking about on carbs and stuff.
I've rebuilt a quadrajet on a 307 Olds but I'm no authority on setting them up.

Well I'm the guy who says fuel injection beats a carb every time. It has kept me away from carbonator service questions until now.:devil:

OK, the reason we told you to rebuild the carb yourself is this is exactly what happens when you start playing the parts swapper game. You just spent good money to have the problems taken care professionally. Take the car back to where you got it fixed and demand that it work correctly without spending any more money. They already had a chance to check the car and give you an estimate which they did. If their guess does not fix the car then they should eat it. Without seeing the car all I would be doing is guessing which I try not to do. I'm not going to throw out a laundry list of possible problems just yet! Don't try to diagnose the thing, let the shop do it. Write out a slip of paper listing your complaints including whether the car was warm or cold, the outside air temperature and anything else you feel important. They already want to throw another rebuilt carbonator at it. BTW if you tell them that the car starts right up and then stalls when cold they should suggest leaving it overnight. If they don' then that is a red flag. Tell them that you don't want the car back until it runs correctly.
This reminds me of when I used to do this crap for a living. We finally gave in and started rebuilding every carbonator in-house to eliminate the roll of the dice when using rebuilts. Hopefully, the next carbonator solution in a box will work. If it does not then we can play the guessing game. Maybe they don't understand how to adjust anything or have mis-routed a vacuum line or 2. BTW there are at least 2 other people on here who just worship this exact fuel system. I have worked on several of these but do not consider myself an expert. My definition of expert is one who has made all the mistakes.
Good luck.

Yeah well they're getting that new carb and it's totally free. The real problem is it starts cold perfectly fine but the fast idle is too high, then i can drop it but it's still high. If the car is driven long enough for the engine to properly heat up then it sits for about an hour the car will not continue to run and will stall. Which the shop tells me is because it's rich. They've seen it fast idle, and they've seen it stall and the best they came up wih is the carb is bad and they wanna get another in there. At this point it's in their hands and I'm not shelling out anymore money for this.

Interesting turn of events.... Today the car ran totally fine. No CE lights, started normally, ran great. I'm puzzled maybe that carb just needed to be broken in or something? I dunno, should I still get the new remaned carb? Car seems to be running fine.... *Shrug*
