2007 es 350 ul, 153,000 miles: A couple of months ago the check vsc and engine lights came on a few days after getting a new set of tires. Car ran fine and lights went out a few days later. This week the lights came on again, the next day I could feel a vibration coming from beneath the car and then the engine light flashes. I drove it to the mechanic who ran a scan, codes for every cylinder came up. The next day he could not find anything wrong with it and the lights went off for him. They came on again as soon as I left the parking lot. The only thing that might be related is that my son ran the car out of gas on sunday, some old gas was put in, less than 4 oz, car wouldnt start til I put 2 gallons in. Lights came on the next day, two fill ups since them. I'm really worried.

 

What were the codes. If you have the numbers please post them. Do you have a "cylinder misfire" on each cylinder. If so it sounds like you may have plugged the fuel injector nozzles. 1st get the codes and then we can go from there. You might want to get some FI cleaner and put a few bottles in the tank. I would use TECHRON FI cleaner and see if this starts to fix the problem. Like I mentioned , what are the codes.
