Ok my car is a 1986 dodge 600 and I have a problem where not everytime I drive it but mos the time it will die when I apply the brakes to slow down or to stop I have to throw it in neutral and rev the gas to keep it from dying at stop lights or going slow. Thought it was the fuel injection so I put some fuel injetor cleane in it and some sea foam. It seems to do it more when my gas is low.

You may have a vacuum leak, get a can of spray gumout, spray the vac lines and maniflod area, when the idle changes, youve found the leak! You want the engine running and spray on the outside but do direct the stream onto the hoses, if it is a vacuum leak, the engine idle will change speed, then you have detected a leak, repair the vacuum leak and see how it runs! When was the last tune up? Filters?
