I’m getting a P0171 code on my 2015 Ford Escape, and it says the engine is running lean on Bank 1. The car’s idle is rough, and my fuel economy has taken a nosedive. I’ve checked the air filter and cleaned the MAF sensor, but I’m still getting the code. Could it be a vacuum leak or a bad fuel injector? Any ideas on where I should check next?
