Found the emissions problem-now need DIY for lower intake gasket
This is both a follow up to an earlier thread I had and a request for help. My 1997 cobra was throwing p0171 and 174 codes and gas mileage stunk. O2 sensors reading a lean condition and pumping in more gas, so I tracked down the air leak to the lower intake, currently front left. I have done this work before on a 1992 5.0 and and 4.0 OHV but not this engine. I am looking for gasket recommendations, DIY, and any special tools needed. Thanks for your help

As for the gaskets, I used OEM Ford ones. For some stupid reason, they sell them as singles and you need two to do the job properly...
