2003-2004 are unusually good years for the XC70. BUT, the computers do have a heat sink problem, meaning that they can overheat and degrade. Normally when the ABS fails, the speedometer goes to zero and stays there. The instrument cluster computer and the can-bus module are failure prone, xemodex.com has "fixes" for them.

The lean condition is usually unmetered air entering the intake manifold, or a dirty MAF.

Take a look at the tranny fluid, it should be pink/red and not brown. A 'hard' shift could be a result of the CCM failing to send the speed to the ECU, rather than a solenoid failure.

Better diagnostics from a VOLVO scan tool will help.
