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.

Code P0401? Pull the egr off, clean the port under it all the way to the throttle plate, I use a length of steel coathanger. Put it all back together, reset the codes, if light comes on again, replace the EGR position sensor.
