    I finally got to clean up an directly test the air injection pump an diverter both showed to work as directly tested.Its a 06 4cyl 2wd ...I CLEARED MAF , AIR INJECT ,PURGE CODES.
    I also checked all hoses for leaks..
    Purge tested good too when direct power.

    Not sure on maf an air injector reading though.

    Are these normal readings -?

    .369 at idle on MAF an .5 as i gave gas to 1rpm
    AIR INTAKE TEMP 55°
    COMMAND PURGE 22.9 at IDLE


    Secondary air status ~~0 stayed on 0 NO MATTER IF GIVING GAS OR NOT..-- NORMAL?

    I put new air filter in too.

    Any info is appreciateed.

    Assuming that's in Pounds per Minute (lb/Min) which would be 2.79 & 3.78 Grams Per Second (g/s) those numbers are pretty close, typically hot idle no load (~600 RPM) you should see MAF Grams per Second be about equal to the engine displacement in liters. So 2.7L engine you would want to be right at 2.7 grams per second MAF.

    Intake air temp should be within about 5 degrees of ambient temp when the vehicle has sat overnight, it will increase somewhat as the engine heats up.
    Purge command will vary depending on driving conditions, it's not really a parameter to get concerned with.

    The Secondary Air Injection System only runs for 30-60 secs on a cold start, after that it is not used at all so no surprise it's not doing anything.

    Are you still getting codes?
