might b ur alternator goin bad

Check to see if your heater core is stopped up. To do this, start the car and warm up the engine. Turn the heater on and turn the temp up. Raise the hood and locate the two heater hoses on the passenger's side going through the firewall below the windshield. Feel both hoses with your hands. If one is hot and one is cool, then the heater core is stopped up. Turn the engine off and let it completely cool. Disconnect the two heater hoses and blow through one and then the other with an air hose till it is clear. Reconnect heater hoses. If this is not the problem, then listen for a clickin noise behind the dash while the car is running and the heater of air is on.

What I don't understand is why mechanic said it would be hard starting in cold, if he actually fixed the choke. My guess is that there is still something wrong with the choke. If you pump the pedal 2 or 3 times, then put to floor & let it up slowly, before starting cold, does that help?

When the pump heats up it will quit working cause the pump on the inside is not pumping fluid to the rack pinion or your racket pinion is going bad. Have you checked the fluid level?

the howling sound could be a window with a little opening, check if your window was totally closed. the clunkin? or clickin sound you hear could be the road salt or ice thats being thrown to your mud guard by the wheel. anyway an actual inspection is recomended, pep boys can do a courtesy check for free.

I never heard anything like that before

Morning, I found your problem...its going to be your fuel pump. Allow me to explain. When you start your car in the morning the car starts just fine. As your driving the fuel pump will eventually get hot. Therefore the circuit cuts off when you turn off for a while then you jump back in to restart the vehicle and it doesn't. The reason is when the fuel pump gets hot it shuts off due to circuit wire inside the pump.
You can almost say like overheating. Therefore your pump is going out. Replaced 7-10 of them in my time as a mechanic. Do yourself a big favor. Don't get a used on or Autozone. Pep boys or Napa will do just fine. Goodluck.

Your fuel injection pressure is probably leaking down causing gasoline to leak into the cylinders and resulting in a hard hot starting condition due to "flooding" of the engine. Try holding the accelerator pedal all the way to the floor of the car like your trying to go maximum speed down the highway and crank the engine for 10 seconds or less at a time. That tells your computer to enter the "clear flood" mode and stop injecting gas into the engine. Ask your repair shop to measure the fuel pressure and see if the pressure is bleeding off too rapidly.
