Check Engine Light - (CEL) came on, had two codes, P0171 an P0174. Indicated the mass air flow sensor. Part from auto store approx 98.00. I opted for the CRC Mass air flow sensor cleaner for $8.00. This takes approx 10-15 min to clean. In my case this solved my problem, and the light has not been back on in 3 weeks since this video was made.
Hope this helps save you some time and money.
