Dies at idle,fluctuating idle in neutral and park,

You could be driving down the road perfect runs good but come to a stop sign or a red light you hafto put it up in neutral to keep it runnin like it doesnt want to idle its really worse at night with the headlights on like it doesnt want to idle at all in drive, ive tried doin what my owners manual says to do about resettin the idle and fuel trim but it hasnt helped a bit im kinda stumped....also when you have it in park or in gear with the headlights and fog lights on they are really dim an you can rev the motor up a bit an they brighten up...
as for codes when it dies it hasnt set any....im so confused

My 1993 buick park ave stalls when stopped at red lights


When was last "healthy" tune up? Plugs, wires, ALL filters including FUEL filter? I'd start there, and run a good fuel system cleaner w/next tank full of fuel. In winter, with fluctuating temps, condensation (water) forms in fuel tank and spark plugs don't burn fuel/water efficiently causing stumbling and premature wear on your plugs.

1992 Dodge 250 van, 318, Automatic - Dies when coming to a stop


I cannot see how adding a fuel additive would help to be honest. I would be looking for a split or leaking vacuum line, I have even seen a leaking evap canister before that caused a similar problem. Does the engine pull clean and strong when it is warm or at cruising speeds? Does it feel like its running lean or misfiring?

Engine stalls at stop lights and stop signs


sounds like the torque converter lock up might not be disengaging. You might also want to check for engine vacuum leaks. Does engine idle smoothly when in park or nuetral ? if the idle is good I would suspect torque converter problem.
