To adjust the air-fuel screw on a Yamaha YZ400F, first, ensure the engine is warm and running at idle. Locate the air-fuel screw, typically found on the carburetor, and turn it clockwise to lean the mixture or counterclockwise to enrich it. Make small adjustments, about a quarter turn at a time, and listen for changes in engine performance or idle quality. After adjustments, always test ride to ensure optimal performance and make further tweaks if necessary.

what i would say is follow all of the fule lines and make shoure they are not rusted on older comaros the fule lines run along the bottom of the frame so when it rains water drips off of the frame on to the fule lines which will causes rust or check the fule relay
It could be the fule pump or the wiring harness for the fule pump.
i have a 1990 ford ranger and my fule gauge always reads full, why?
what kind of fule pump is in a 1992 ford tempo
it depends on what kind of fule delivery system you have. if it is carborated then it could be because your idle screw is not set high enough and carb engines have to warm up befor they run good in cold weather. if it is carb, engine YOU MIGHT WANT TO ADJUST THE SCREW AND LET RUN FOR ABOUT 5 MIN IN THE COLD. IF IT IS A THROTAL BODY THAN IT COULD BE A HOLE IN ONE OF YOUR LINES AND WHEN IT IS COLD OUT IT WILL CAUSE IT TO ACT UP MORE NOTICABLY THAN IN WARM WEATHER.
Drain the fule tank. Plug on bottome of tank. Lift matting over tank. There is a plate hold the fule tank in place. Remove from top of fule tank.
The fule line is usually a pair of tubes that runs up the drivers side frame rails from the fule tanks to the engine compartment. the lines run up the fire wall to the fule injection rails. If this truck is Carb the fule line should be in approximately the same place.
