Engine Mechanical problem
2001 Daewoo Nubira 4 cyl Front Wheel Drive Automatic
I've been working on my friend's Nubira, which has an engine trouble code of 0440, which indicates a large leak in the vacuum I guess, and so can't pass emissions. I tried replacing the gas cap because I've been told that is often the culprit. The cap was only $8 at autozone so I don't know if it's just cheap or if it's something else. I've been told it's possibly the Purge Valve. Is this the same as the Vapor Canister Purge Solenoid? How would I know if it's that or something else? Also, how do I check for leaks in the fuel lines themselves?
have the same problem?
