I recently had a code for a misfire in cylinder 1 & 2. I replaced the plugs, ignition wires, coil pack and fuel filter. The car drove fine for a few hours and then started misfiring again. I had the plugs checked again and everything seems fine. What would cause it to still misfire. Mechanic feels the ECM may need to be replaced. Any ideas?
