How is the cold weather related? My Mark has never ran better now that the temp here in NE Fla is below 32 degrees. In normal weather it will miss under different conditions, even after replacing all COPs. I've SeaFoamed the fuel system and the top-end with no change. Is this miss an ignition control module overheating problem? An injector or injector gasket vacuum leak causing the P0156 (O2 bank 2 sensor 2) CEL?
