How expensive is to fix the computer on my 05 Malibu

SOURCE: check engine light comes on

Do you hear the air pump run when you start the car? No? Check the A.I.R. pump fuse in the under hood fusebox. if it is blown then you probably need a new air pump motor. If the fuse is not blown then the relay could be the culprit. if you can hear the pump running when you start it the engine then you probably just have some wiring issues from the relay to the ecm it can still work ok but fail the resistance test that the computer runs randomly. Give some more info and I'll help you through this.
Good luck.

SOURCE: I have a 2005 Chevy Malibu. The check engine

"This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine."
Hope that helps..
