I'm having some carburetor issues.?

It's a 1984 Honda Accord. I just moved from CO to TX, and it started as soon as I got down here, so it might be an altitude thing?

What happens is this: I put the car in park, and it's fine. I am driving down the road, and it's fine. When the car is in drive but I have my foot on the break (like at a stoplight) it DIES. the rpm just drops down to zero and the car is dead. So I restart it, and keep it in neutral while at stoplights, because it runs the smoothest in neutral. It also dies almost all the time while in reverse. Also, my mpg has gone waaay down.

I put some of the carburetor cleaner stuff in it and have tried switching grades... any other ideas?

    Check your vacuum lines, going to the distributor and power brake booster, namely, and replace any cracked or blown hoses. Then make sure you have no open vacuum ports. If you do, either find what should be plugged in or cap them.

    The altitude can have an affect on carburetor-based engines, since the carb needs to be adjusted for air density. If vacuum checking doesn't help, you will need to tune your carburetor.

    If you don't know how to tune a carburetor, I would suggest searching for a question specifically about that, looking up online videos, or find a friend who knows how.

    If tuning doesn't help (and it should), then you may need to rebuild the carburetor.

    block the wheels and put it in drive and turn up the idle screw. sounds like it,s not idling fast enough.
