yooo,
okay i have a plx m-500
lets say im driving in 4th gear right?
and i just let off the gas, my wideband reads "air" what does that mean??
like its just reading air because im not on the gas??
 
This is completely normal, mitsubishi gave us deceleration fuel cut to help engine braking and save gas. Most widebands will just peg out lean.
 
Yup as stated it shuts off fuel when ya let off the throttle. Then cuts back on once engine hits a low enough RPM -to keep the engine running
