Thanks for the link Rockledge! I'm still looking for a pic of the fuel rail manifold gasket. Taking off the whole assembly (throttle body and all) looks like the way to go.

Does anyone have the OEM or aftermarket part number for the Fuel Rail to Intake Manifold gasket? I've found the Manifold gaskets and the ignition plenum gasket part no's but can't seem to find that one at Advance or Auto Zone.

I had a mechanic clean out the throttle body, change the plugs, and replace all the filters last spring and that's when the CEL for 171 and 174 became much more frequent. I was wondering if maybe the new fuel filter might have contributed, but I think since I have the 1997 model the air leak is most likely so I'm looking to the possible damaged Fuel Rail to Intake Manifold gasket. Thoughts and questions are welcome.

Thanks,
