So here is the entire low down on the car issues... 1994 Chrysler Concord, 3.3L engine, over 250,000 miles. Just recently the car was bucking and backfiring so I checked the codes with the ignition key and the O2 sensor was bad. The car was also in dire need of a tune up, so along with replacing the O2 sensor, the spark plugs, spark plug wires, fuel filter, air filter, oil filter and oil were replaced at a small town car repair garage. I drove my car home ( 12 miles ) and it ran perfectly fine, showing none of the problems it had before. So, a few hours later, I get in the car to leave home, start it up and when it starts, it smells like a rich mix of gas and exhaust and it's running a bit rough. I try to drive away and the car stalls. Try to start it up again and nothing. It will turn over, but it won't actually start the engine. If I put my foot on the gas and press it flat to the floor it will start, but as soon as I let off of the gas pedal, it will stall out again. Try to restart the car and the whole cycle starts all over. If I let it sit for awhile ( more than a few hours ) it will start again no problem, but again, if I try to drive away, it will stall and not want to restart without smashing the gas pedal to the floor.

So, does anyone have any valid suggestions as to what may be causing this problem? The starter and alternator were checked and they are fine. I just put a brand new battery in the car the day I brought it back from the shop and I checked the fuel pressure via the valve on the fuel rail and it is fine. There are no codes showing up with the ignition key either. Any and all suggestions would be greatly appreciated!
 
Sounds like its flooded when you hold the gas to the floor while cranking it puts it in a clear flood mode where it does not inject any fuel while cranking so it can burn out all the fuel left in the cumbustion chamber, try doing this a few times to get it all out then see if it runs good again after that.
