I have a 1992 olds 88 runs fine when its cold but when it gets warm it wants to run bad back firing missing ben working on it for weeks replaced mass airflow tps and air sensors also notice that radiator fan runs all the time and sometime my heater blower comes on when it wants to last but not least when open car door interior lights come on and stay on olny way to get them off is disconnect battery when reconnect they stay off until you open door. thank you dale diemer

Sounds like you have a bad ign. module. When the engine is cold moisture causes the miss and when the engine warms the module shorts out all together.

replace the ignition module or pickup coil located under the distributor cap ignition modules work when cold and will stop firing when they are warm when they r going bad

when's the last time you did a full tune up? (air and fuel filter,plugs,wires, cap, rotor) or could be a number of things. i would look at the temp sensor. i believe when they fail, they peg out all the way cold or all the way hot. so your car thinks it is still cold, when you have reached operating temps, causeing your misfire. good-day !

idle air control valve does your vehicle have one check to see if your geting the correct amount of fuel at rail sounds like a fuel issue cloged injector

the temperature sensor for the auto choke could be playing up so its staying on choke ,or the idle control valve ,

Is the Service Engine Soon (or Check Engine) light illuminated on the instrument panel? If so, then have someone pull the codes and post them back here. Autozone will do this for you at no cost.Caution: don't purchase any parts after reading the codes on their recommendation! If no codes, then suspect either a bad crankshaft sensor or camshaft sensor. There are other possibilities too, but these are primary. I have seen MANY bad crank sensors do exactly what your describe without setting a code.

SCAN IT CHECK.FOR A FAULTY FUEL PUMP OR RELAY.

Replace the ignition module.

Replace the acceleration pump. It's a small diaphragm on the carburator, near the fuel line. Usually less than $10.

Try replacing the coolant temperature sensor for the injection system.
