Just had oil changed, ran out of gas at the dealer and now check engine light is on, code P0171

We have a 06, with 170k miles. Oil has been changed regularly at dealer with Mobil 1. Never had an issue. We tried a new dealership today (closer to my husbands work place). He was running late to the appointment, knew he needed gas, and guesstimated he would have enough to get gas after the oil change.

They changed the oil, drove the car out to him and it ran out of gas. They put some gas in, fixed a squealing noise my husband pointed out was not there when we arrived (supposedly spilled oil on a belt?) and he was on his way.

About 30 miles later check engine light comes on. We were far enough away and too late at night to turn around and bring it back, so I brought it to Autozone to run the code. Code is P0171 lean condition bank 1.

Any insight? We are headed back in the morning, but wary and want to be prepared....

Thanks in advance!

 

Thanks so much! That makes sense and alleviates some stress...hopefully that's all it is

It is driving pretty much the same, no hesitation. The only thing I'm noticing is a whining sound (like an extended high pitched beep) when I'm pressing the brake at speeds under 35...I've never noticed it before (but not sure if that's because I usually have the radio on...though it was detectable even with uh radio on...)

 

huh...who knew....guess I just need to turn my radio on louder...lol
