Hey when the motor is cold and i start it up (summer here) it will idle fine but like every 5 seconds you would hear a pop in the exhaust like backfire. When i go to drive the car it stutters and coughs and misses and runs like its on 3 cylinders when I put some throttle down. I drive the car until it goes into normal operating temperature and the misfiring goes away. There are no codes thrown. Plugs arent really fouled. Running stock ECU. Leads are quite new. It's definately something to do with the ignition. Either plugs or something in the distributor or maybe even the o2 sensor? What do you guys think? Only happens when cold.

Cheers guys, happy new years~!

 

Are all your plugs, plug wires, cap and rotor OEM? Even brand new aftermarket stuff can cause problems.

Plugs are NGK, wires are NGK, cap and rotor appear to be OEM. It doesnt happen everyday. Just randomly...
