how can i resolve check engine light on 1999 chevy malibu?

[jcyrus6]

check engine warning shows erg valve but after replacing the valve, the check engine light came back on. What else cane make the malfunction warning for erg valve?

 

[Juggernaut™]

if the computer trouble codes are not cleared after replacing a faulty part the light will come back on. some codes are short-term memory but more critical codes are long-term

put duct tape over the light

Take it to Auto Zone they will check it for something you may have missed.

They will check it for free

 

[?My 2 Cents?]

well sometimes after so many miles it will stay on, take it to a shop and have a computer hooked up to it, that should pin point why

We changed our's four times (two year span) till we found out it was the coil pack that was bad.
