I have an engine light that will not reset. I have replaced the EGR valve twice, plugs, wires, timing chain, water pump and oxygen sensor on exhaust manifold. My gas mileage is poor and I cannot get an inspection with the light on. Can you give me any ideas about possible solutions to this "low flow by EGR valve" engine code. The car gives off a puff of blue smoke when it starts from a cold start now also. When hot it does not give off any smoke and I don't appear to be burning any oil through the engine as the level is not changing any.
