Hi Scotty. Thank you for all your videos. Much appreciated. I have a 2009 Ford Ranger 4x4, XLT that has an engine light on. I went to 2 mechanics and they all didn’t find anything wrong. They changed the ecm, air flow sensor and nothing changed. They checked everything and it all seems good. When I put it in parking mode, the air intake box where there is the air filter chokes. And most times it responds late when I hit the gas. The last mechanic I took it to, said when he takes off the air flow sensor plug, the truck runs great but when he puts it back, it starts acting up. I run the OBDLink and it indicates, running lean, MAF low. The code is P0102. Do you have any ideas? Am out of ideas. Thank You
