Installed new egr valve, new bpt valve, new egr solinoid and new exhaust temp sensor. Also new oxygen sensor, new plugs, cap, rotor, air filter, new fuel pump and fuel filter, new iacc valve, all new injectors. Problem goes away if I unhook egr valve vacumn hose. It feels like egr is opening too far.
