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.
