Check engine light after using Sea Foam Spray in a Ford F 150 [SOLVED]

My truck is a 2012 Ford F 150 with a 3.5 EcoBoost. I just finished using Sea Foam Spray by following the can instructions and now I have a check engine light. With your knowledge of doing these engine sprays what could be causing the engine light to come on?

Thanks for the question James. Using Sea Foam Spray through the upper intake can cause misfire codes during application. It’s just your engine computer noticing something irregular going on in the chambers and doing its job. The codes will typically reset to normal within 20 or so miles of driving (after the application). No worries, anyway.

I just had a cleaning done using Sea Foam and I have a check engine light for mass air flow and O2 sensors; the misfire you explained, but what of the sensors?

I sprayed Sea Foam Spray into my throttle body as directed. I did everything and now I got a service engine light on. What could it be? Could you help me please?
