    CEL code P0172

    Hey guys. First let me say, this is obviously not a cb I'm asking about, but rather a 97 accord. Either way, it's still and accord and this forum is full of knowledgable people. So here's my situation. I have a 1997 accord ex with the f22b1 vtec. I have a bank 1 too rich code that keeps coming back and I need it gone due to up coming emissions testing. So far I've replaced my front o2, plugs and a new air filter. I checked to make sure my thermostat was working, which it was. Car does reach normal operating temperature just fine. A little below half on the gauge. Still no luck. What else could it be guys? I've searched and searched with the next possible problem being a faulty MAP or faulty coolant temp sensor. Any ideas? Thanks guys!

        Unfortunately, the 98-00 Accord's included in the service bulletin are 6th gen Accords, while the 97 was a 5th gen.

        It does illustrate the complexity in fuel system control and how hard it can be to run down a problem.

        Probably best to get a service manual and just start following the steps in the trouble-shooting section.
