[autox615]

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!
