Hello every one,
Does any body knows how long the secondary air pump should run in a cold star ?
My is only running for 10 to 15 seconds max the check engine light keep coming buck on the dash.

Did any body had the same issue?
This is what I done
Pump is good I tested
Valve good
Clean the intake area where the valve seats
Replace the two 02 sensors
And the light keeps coming back on

Any sugetions

Thank you
