So I just got those codes thrown at me from the ECU. They mean Cylinder 3 and cylinder 4 misfires.
As far as I know that means I may have a couple of bad (or marginal)
1- spark plug
2- spark plug wire
3- distributor cap/rotor

am I missing any other possibility?

thanks

 

could be anyting man. low compression, head gasket is shot. ive had a 73 for a while now, and have chaged all the above that u listed. could be ur injector. i think myy prob is a dead cynlinder

 

I don't know about replacing that stuff yet, what about the mileage on the car, and these parts. Are you using anything aftermarket ignition parts?

 

I've had that stupid light on forever now... I think it might be my ignition timing. I need it checked and adjusted I think.

 

the car has 105k miles, and the spark plugs and wires have about 50k miles (about time to change them). The distributor cap and rotors have about 10k miles.
I maintain the car pretty meticulously since I take it to the track on occasion for HPDEs. I reset the ECU yesterday and I have not had the code pop up again. I am probably going to change the aforementioned parts anyway and see if anything comes up.
thanks for the help guys.
