Have a 1996 Dodge Viper RT10. Runs rough when driving, loses power, and hesitates at times. OBDII codes read p0171 and p0174. Can anyone help out, and troubleshoot this with me?

 

Well first of all its an emissions problem.Second if it loses power when you drive it, it could be a catalytic converter that is geting clogged&/or bademissions sensor. The P0174 number is for an Auxillary emissions control. But both P0171 & P0174 tie into the transmission since that is what the 7 is for. . The numbers 1 & 4 are for Fuel control(1) and Auxillary emissions(4). Have things looked at on a "sniffer" machine that measures your CO2 & O2 etc etc
