Recently the car has been having an ocational missfire and smells a bit rich. In the mornings i'll start the car run for about a min or two then die start it once or twice more and it stays on. Once hot if i put a load on the engine either lights or the heater fan kicks in at idle at a stop she starts seeming to be struggling to stay idling well. Any sugestions or routes of checking? I planed on doing plugs and wires on it soon. But wondering if it needs more then that.
Most misfire issues are related to old plug wires, improperly gapped plugs, or a cracked, worn, or corroded distributor cap.
If you have a multimeter, your plug wires shouldn't measure more than 10K ohms per foot of wire... so no more than 20K - 30K ohms end to end. If you don't have a meter, then simply spray some water (mist) over the wires while the engine is running at night and watch to see if there are blue sparks jumping from the wires to the block or other metal. If so, that's a sign the plugs gaps are too large or the wires are too old.
If you don't get sparks, then remove your distributor cap and have a look at the posts inside... they may be covered in white or green powder. Clean them off and that should solve most of your problem.
(Edit spelling... turns out there's no such thing as a mullet-meter)

Well, with code 13, your O2 sensor isn't working so you're running in open loop all the time and it's no wonder you're getting poor fuel economy. Code 21 means your TPS isn't working, which is a major sensory input device for the ECM to calculate the amount of fuel to spray, and Code 44 is probably just a reaction to the TPS not working. (Code 12 just means your ECM is working fine). Certainly start with the known problems before trying anything else.
@bloozberry alright tomorrow get paid so starting with plugs wires and the O2 sensor possible the tps sensor. If i've got enough going to check the timing of the distributor as well. Other then that noting i actually had a stall even hot. But as i checked today codes are consistent 12 13 21 44
