The engine runs ok most of the time but when it has a hesition the tcs lignt and sometime the tcs lihgt comes on. I have had the codes checked and was told it was the sensor on the air cleaner. I don, t understand how this causes two different lights. Thanks hb.

The sensor I think you are referring to is the mass air flow sensor. Having the same problem with mine. Also check the idle air controller and your intake hoses for cracks/holes.
