Quick question

[David Williamson]

So I just found out by the seller of my car that he actually made my idle higher in my car, I was wondering if I should lower it because I read this "A poorly adjusted vehicle can stall, have performance problems" That's why my car has been stalling and running very sluggish and not wanting to get up and go.
I was wondering if I could be right and I should lower it or if I should just leave it alone, Me in general is wanting to lower it but not wanting to make a hasty decision and messing something up, because I really don't know how to either so I would nee good instructions first off.

Thanks in advanced, God Bless and be safe.

If the idle was adjusted to make it idle higher it shouldnt make your car stall and perform poorly. It just raises your idle speed. I dont know what carb you have but typically you just turn an idle adjustment screw and it pushes the linkage back to open the throttle.

My guess is he raised the idle to cover up a rough idle condition. I solved a similar problem on an 86' MC by lowering the idle to what it should be, (and it ran very rough), then richening the idle mixture screws, turning them out (counterclockwise) while watching a vacuum gauge. Smoothed right out. Contrary to popular opinion, the CCC carb can be richened slightly, and the computer will adjust to it.

Oh okay I was just on a website that talked about it and that's what it said so I put that there to show what it said and I was having them problems so I thought I would ask you all to get exactly what you all would say.
My car will stall at red lights sometimes it will put put and just die out, but will start right back up when I start it.
Sometimes I have to push the gas a little while holding the brake cause I can tell its starting to put.
I have what came in the car when it was first built.

I have no clue why he did it, I think I remembering him telling me why but couldn't put my finger on it.
I mean it runs great just a few little tweaks and was told it could be the carb so I thought to ask, more knowledgeable people on it.
but I think it was something about it not starting, he said it would die out when put in reverse or drive.
Which it still does that now.

I am honestly scared to do it myself because I don't want to mess something up.

Well, that's a smart move. Don't mess with it if you don't know what you are doing. Best bet then is to find someone on this board close to you who does know what he's doing, or find a shop with an old timer or hot-rodder who know how to play with the OBD1 system. You may only need a simple adjustment, or a carb overhaul. Mention what I suggested, it worked for me.

and don't let anyone talk you into a non feed back carb if that's not what you want..there are plenty of the feed back carbs working well on cars out there

I am going to take it to this shop around the corner they specifically work on classics like 40' to 80's cars and their all pretty much old timer guys who love old schools.
Yeah I mean it sounds easy to turn some screws but I would rather let a person with skill do it for me haha, But thanks again for all the help.

Okay I will make sure to tell them not to sell me anything I don't need.
which I will tell them I don't need it cause I am sure it cost more then I have to give away.
