Re: car not running right
Check the catalytic converter to see if it has restricted flow, i have had the same problem in the past with a car, it would start and idle great, i could rev the car up but the minute i put it in gear it wanted to die, and my cat was clogged

Sounds like the veh is loading up on fuel make sure coolant sensor to computer is reading right it could be choking the car.Also check for clean throttle body But what the most likely cause is the mass air flow sensor. Blow it out now do this gently there is a wire in there thats what you want clean. dont spray any liquids on it THANK TIM
It could be a couple things. There may be a vaccuum leak in the fuel system such as a bad EGR or PCV valve or the throttle position sensor. I'm leaning towards the throttle position sensor needing replaced. The throttle position sensor reads how far you're pressing on the gas peddle and then feeds that to the computer telling it how much gas to feed to the engine. If that sensor isnt working right then your car will get enough gas to start and idle but will starve for gas as soon as you try drive and will then stall.
check for vacuum leaks at throttle body gasket. pvc valve stuck open.if all is good .change fuel filter .if still stall out check fuel pump pressure.if all is good .replace plugs and wires if they have not been changed.
the car's computer needs to relearn it's correct idle allow to run for several minutes and the computer's RAM will return and idle will be fine. On the automatic transmission it may take several miles of driving to shift normally as the computer learns and adapts. Loss of battery voltage can cause all sorts of running problems until this happens.
