Today I cleaned the mas sensor thinking the cel can turn off .I have an injen cai and thought oil from the filter can had reach the mas sensor.Well I had to make a notch with my dremell tool to remove one of the screws. Then I use a q-tip swab to clean the sensor and found no oil and just dust . Installed the sensor back and turn on the car and found it can not stay on , it just sounds and smells like its too rich and dies again . I disconect the mas sensor and it runs the same way!
Its there any form to test the mas ?I can not imagine that a swipe with a cotton swab can kill it ! Any ideas ?

 

Sensor bad and extended waranty will cover including the rear shocks. End of story !
