Oldsmobile/Buick Repair: engine not running on a regular basis, oldsmobile cutlass supreme, electronic ignition control

Question
I have a 1991 oldsmobile cutlass supreme with a 3.1 liter. In the morning when its cold outside it starts but wont idle and if you keep the rpm's up it runs rough but after it warms up a bit it is fine, and will run just fine to work or where ever i need to go. In the afternoon  I can get off work and go pick up my daughter from school which is about a mile and a half away and then go home and it is fine , but if I go anywhere else it will die and you have to sit there for a few minutes and then it will restart. It will restart if you hold the gas pedal down but it blows black smoke and you can smell the gas.The speedometer and tach works when it wants to as well. I have replaced the mapp scensor, tps, and the air flow scensor as well as the electronic ignition control module. Occasionly it backfires as well. Today It would not restart for quite awhile and I took a gallon of water and poured it over the intake manifold and it started right up and had it got me home.

                        Thanks for your time,

Answer
HI MIKE.WELL IT SOUNDS LIKE YOU HAVE A BAD TEMP SENSOR.IN THE FUEL INJECTION SYSTEM.THIS SENSOR TELLS THE PUTER WHAT THE AMBIENT TEMP IS AND THEN ADJUST THE FUEL SPRAY FROM THE INJECTORS.IF IT TELLS THE PUTER THAT IT IS COLDER IT SPRAYS MORE FUEL.IF IT TELLS THE PUTER IT IS HOTTER THEN IT ACTUALLY IS THEN IT WILL SPRAY LESS FUEL.WHEN YOU SEE BLK SMOKE IT IS TELLING THE PUTER IT IS COLDER THEN IT IS..BE SURE TO ASK YOUR PARTS PEOPLE FOR A TEMP SENSOR.AND NOT ATEMP SENDER TWO DIFF PARTS THE ONE YOU NEED WILL HAVE 2 OR 3 WIRES THE WRONG ONE WILL ONLY HAVE ONE WIRE.PLEASE TAKE A MIN TO VOTE ON MY SERVICE..TY BILLYMAC
