    It looks like I will be buying a car with a 2.3 liter whipple. The whipple has about 35K miles on it. Is that a lot of miles for a whipple?

    Check Engine Codes P0172 and P0174

    What could be some of the causes for both of these codes to be on at the same time? Also these codes have been off and on for about 2 years. Is this potentially dangerous? This is happening to a car I'm possibly interested in buying. These codes are bank 1 too rich and bank 2 too lean. Thanks
