What engine do you have?

Still recommend you get OBDFusion, it can tell you a lot about what is going on. Just because there is NO SES/CEL/MIL does not mean everything is operating properly with the engine.

I doubt the problem was with bad fuel, usually you have more obvious problems then Lean codes.

If you own or drive a 1996 or newer vehicle, you NEED your own OBDII tool and for under $20 it is a no brainer!
