I dont know what else it could be. I need
help, i also cleaned the throttle body. And

Is the CEL on? If it is indeed a misfire, those are caused by the ignition system. Coil, spark plugs, wires
The check engine light is on. I was told theres a misfire in spark plug #1 could this be the coil since the spark plugs are new
