2011 LR4 with 118k miles. Owned this truck since it had 18k miles, no previous engine problems. I was driving to an appointment yesterday and was running late as well as was almost out of gas. Usually never get below 1/4 of a tank, but got the “low fuel” notification while en route, so i stopped and put half a tank in from a random gas station along my way. Would say I had about 15 miles until empty. After my appointment, about 3-4 miles away from the gas station, I managed to get about 2 miles down the road and was sitting at a stoplight when the vehicle started vibrating abnormally. I look at the dash and see my RPMs fluctuating, check engine light comes on and starts flashing (misfire I presume from previous experience, as well as would explain the rough engine idle), “Reduced Performance” notification, as well as a slight smokey haze coming from the exhaust (smelling strongly of fuel). I pulled off the road and got the truck towed home. I’ve since started the truck a handful of times, but hesitant to let it run longer than 20-30 seconds because of the fuel smell from the exhaust. I noticed that the passenger side exhaust has a vaporized fuel appearance (doesn’t appear to be oil or water smoke, pretty confident it’s fuel) for a few seconds after shutting the truck off. Oil and coolant levels appear to be normal. The truck did not overheat. I’m going to change the plugs out because they are beyond due. Also going to grab a code reader to get additional info since I don’t want to drive the truck to the parts store to get the codes. I’m considering a seafoam cleansing, but mostly want to get the codes first so I have a better idea of where to start a diagnosis. I know running the tank that low was dumb and I’m kicking myself for it, hoping I didn’t do any damage. However, I’m thinking it could be bad fuel also. Could there be air in the fuel line? I know the codes will provide a bit more insight, but posting for now in case someone recognizes the symptoms.
