What is the code number?
Secondary Air is the term for the "smog pump" system. It is air delivered to the exhaust system to help reduce emissions while the engine warms up.
Evidently you altered that secondary air system in some manner.

Take it off and put the stock equipment back on.
There needs to be some vacuum in the intake system for the computer to work right via the intake manifold air pressure sensor.

Hmm...maybe if youd stop breaking the stuff in car, it would work properly. Also, maybe you should stop tinkering with your car.
