Lousy gas mileage!

Hi

A friend asked if it ever had been checked in the ignition...(I thought the PCM took care of it) - so he checked it and initially he couldn't find the mark that should be visible on the marker (2 cm away) - so he adjusted it - and wroom wrooom...I got a new van!

Yeah, the PCM can only adjust the timing so far. Good find.
