Hi, I recently bought my first car. I found it in excellent condition, and the previous owner took care of the vehicle. I purchased a 2005 Ford Mustang with an automatic transmission and a 4.0L 6-cylinder engine. I bought it with 151,000 miles. Once I had the car, I did the maintenance (most parts were Motorcraft to keep it original to the car) to get it running smoothly. This included differential fluid, transmission fluid, engine oil & filter, new sparkplugs, new brake fluid, new power steering fluid, new air filters, new fuel filters, new antifreeze, and a new serpentine belt. However, a week after I started to drive it, I was getting an engine light for a P2195 (Bank 1 Sensor 1 biased/stuck Lean). I had just changed out the Oxygen sensor for that bank; however, it did not fix the code I have a hunch it might be a leaking fuel injector, but I am clueless. Any help would be appreciated. Thank you
Well many things can make a vehicle run incorrectly. The sensor is just reporting on a problem in the engine so check everything on that back. See if fuel injectors are leaking. See if there's any kind of compression problem inside the engine like a sticking valve or worn piston rings. Pray it's a simple as a bad injector
