Trying to narrow down what could be wrong with my van listed above SE model. The problem is consist of gas smell or carbon monoxide in the cabin as well as rough idling, flickering lights, when stopped at a red light spark plug misfiring, sometimes stalling lack of acceleration puttering and is reading codes P0172 and P0301. I have already changed the spark plugs and spark plug wires.

Good morning

I would start with checking the compression in the effected cylinder to be sure there is not internal engine damage in the motor.

Also, check for power to the injector to be sure there is power to it for firing fuel into the motor.
