So I have read quite a few threads about the code p0449. I am trying to find a definitive answer on what I need to fix. Some people are saying I have to fix a solenoid that is located in the drivers side rear wheel well. Then I real some people say I have to fix a part on the back of the motor. Then I read I need to pressure test for vaccum leaks. I bought a gas cap from GM so I know that is not it.
My job has cut hours and I really can't afford to take the car to the shop, so this is one I am going to have to tackle on my own. Does anyone have a answer to this? Also, if it helps any, since my check engine light came on I am 2 miles per gallon less and it seems like the car is DRINKING gas. Help please!
