I noticed spots on driveway same day the power steering was making noise, and then I noticed engine light on so I put scanner on and it says code 0171 engine running to lean and there’s times when it’ll stall when I slow down to stop or turn or while idling it’ll drop very low and almost stall. I’ve only had this truck for 1 year, it was a gift. But I do know the previous owner always took it in or purchased parts that are east to replace when necessary so it’s never been experimented on. I don’t know what to do from here?
