Question about 1999 Chevrolet Malibu
On a few isolated occasions 1999 chevy malibu (186k) will not start when cold (summer weather). Then not too long after (1 hour) car starts fine. What is the problem?
It sounds like your carburetor is flooding, check to see if the choke is set too tight.
to do this, when the engine is cold, remove the air cleaner assembly, push the gas pedal one time to the floor. in the carburetor throat is a flap, this flap closes as engine cools so the engine receives more fuel for cold weather starts, the flap is at the top of the carb. this flap should have about a 1/8" gap between the throat wall and the flap when it is fully closed, if if is completly closed it will give the engine to much fuel and cause it to flood. if you need to adjust just follow the linkage that the flap is attached to, and it will lead you to the choke housing, this is where you can adjust it.
once this is done start the engine and let it warm up, as it warms up this choke flap should open completly up in a vertical position.
if it doesnt, then you probably have lost power to the choke housing or your heat tube that comes from the exhaust manifold to the choke housing is bent, off or missing. most likely yours will be electric.
i hope this helps, good luck
