Hey guys I need some help, I've searched. Its a s14 obd1 240sx. It runs perfect when its cold and up until its up to temp. Its not throwing a code. The only things I have replaced is the fuel filter, and spark plus. The distributor cap, rotor button, and wires have been replaced in the last 15,000 miles. I also took off the distributor cap and cleaned the carbon buildup off the rotor points and rotor button.Thanks for the help!

the car has 210,000 miles on it but has been kept up, has great compression, and runs perfect ther than the freaking miss!)

check over the resistances in the ignition wires, and have you checked out your cts yet?
