Misfiring in a car when it is cold can be caused by several things. The mist likely causes are a bad head gasket or a leaky fuel injector. Either of these can allow fluids to slowly mix overnight and the car will misfire until the excess burns off.

Why 97 ford ranger hard to start cold after warms up its fine and easy to start?
it really could be a number of things, but more than likely its either the idle air control valve that is sticking, or your transmission fluid is dirty. When your transmission fluid is dirty or has particles in it, the car will idle rough and seem to want to turn off, once it warms up and the gunk glogging the transmission filter is stirred up, the car will seem to run fine. If you let the car cool and that gunk re-settles, it will do it again.

it could be alot of different things, bud. my 89 is doing the same thing and i still haven't figured it out. they say its either the module, or ignition coil. the fuel pump could be bad. a vacuum line could be bad. or there could just be a bad relay.

What will the 1991 Chevrolet lumina do if it has a bad control module?
Could do any number of things. Not start at all. Start and run fine and take random spells of misfiring. Could start and run fine while it's cold then start running worse as it warms up. You can pull the ICM and take it down to AutoZone where they can test if for free. Have them test it several times until it gets warmed up. A lot of times these won't show being bad until they get hot.
