Check Engine Light

I recently removed all the smog equipment from the car. I get the check engine light after the car has warmed up (running for 10 + minutes). The car runs perfect, but this is new.

Is this because of the smog pump removal? Do I need a tune/chip to override this?

Blink out the malfunction codes. Odds are it is for the EGR.

Re: Check Engine Light

If you don't have a code reader or aldl cable you can use a paperclip on the aldl plug to set it into a diagnostic mode. It will blink the error code # when you turn the key forward which you can reference for the actual error its throwing.
