Pre ‘97 diagnostic scan?




The check engine light is present and it is running rough at idle as it is missing. If I apply a heavy throttle, it becomes worse and if I come to a complete stop, it starts shaking. If I turn the ignition off and back on, it runs better but the engine still misses. Before I start replacing plugs, coils, etc., I was curious if anyone else has had these issues and what the cause and or causes were. The car was running fine before I replaced the water pump and thermostat with no warning lights present. I also replaced the air filter with a K&N as I read that the K&N is fine on the C36 unlike the C43. Any input and advice is greatly appreciated!
