Ok here is the car a 1998 ford escort 2.0 automatic. It has me scratching my head It has a "miss" at idle and in low rpms. And does idle rough. But it drives fine. It has no check engine lights or pending codes and the readyness is up. I have replaced the sparkplugs and wires. as well as the coil pack from another car with no change. I have been driveing hopeing it throws a code so i know where to start looking. Any ideas guys?
