egr is only open while driving an throttle open, it could be stuck open. will run like crap an stall at idle, try tapping it too unstick or remove an clean.So now I've hit a bad spot on my little cruze. Recently I was side swiped a couple weeks ago. Not much damage mostly paint scrapes but I take my car to the body shop aka the dealership. Car was running fine when I left it and I get a call a week later you car want stay running more than a couple seconds. They diagnosed it to be a bad egr valve. 750 to fix. My problem is the car was running fine when I left it and it has over 50000 miles on it do out of warranty. Is this car going to be a emmision problem. Car was trouble free to this point . egr has only hiway miles and should of never failed this early. I drive a semi and get a good 200000 miles before the valve goes bad.
