I'm getting these fault codes and am curious about fixing them but not sure where to start.
52- Power steering pressure switch open.
81- Air diverter solenoid fault, intake air control circuit fault / air injection diverter.
82- Air diverter solenoid circuit fault or supercharger bypass circuit...
I bought a 1990 f150, 4x4, and the previous owner put 6" lift springs on it but just put some weird bracket extension on the shocks, and the shocks need replacing soon so I figured I'd get shocks with the full travel. Any idea of how big/how to calculate what size I need?
