It never showed a trouble code until after I had my exhaust manifold repaired and I reinstalled it, the exhaust manifold bolts had stripped out and a couple were missing, which caused the manifold to warp a little. I have attempted to check the egr valve, I revved the engine up to 2000 rpm and checked for movement but did not see any. Then I removed the vacuum hose and revved it up again and there was suction. I don't have a hand vacuum pump to test the valve itself! I have also checked the condition of the different lines. Any thoughts or ideas?
