OBDII code p0171

Replaced the fuel filter and cleaned the hell out of the MAF sensor. Don't just clean the visible bulb you have to get up in there if you look(wish I had pics)you will see the wires are kinda hidden in there clean them good as well with electrical contact cleaner as these wires are what reads the air flow. Once I cleaned it good I left it out to dry for about 30 mins and I also unplugged the EFI fuse it is located under the hood then put it all back together and cleared the code with my scanguage. So far no light it has been two days and about 120 miles on the truck since then.

 

Haha true but as of now the only time it sees 0rpm is when the key if off
