I believe I have a similar problem on my 1997 1.0. I have changed both 02 sensors. Now the falt code goes to EGR. I have taken off the EGR Valve and cleaned it very very thoroughly. I still get an EGR code. Does this mean my next step is to take off the intake Manifold & clean the passages??
Anything else I can do or test, before rippin off the intake??
Thanks
John
