    Check IAT sensor for damage or contamination.If scanner with data scan avail.
    see what temp. the intake air is should be same as temp. outside(ambient).If not
    replace the sensor.

    Check for vacuum leaks . Pull spark plugs (keep in order of cyl they come out of) inspect for irregularities. If in doubt - replace with FACTORY plugs. Have IAT circuit tested for wiring problems , make sure reference voltage at sensor is correct (GET correct specs)
