Hey all I installed my paxton, ran it a couple days, got totally nothing for gas mileage, drove it 4 times in 4 days to see what it did used half a tank of gas and didnt go that far or hammer on it that much! So I unhooked everything now my air fuel meter always reads Rich and I get a code 13 (O2 sensor failure) I just took the car on about a 4000 mile trip and it has a cowl ind hood that is functional, tha faster I went the lower reading I got on the AF meter but just creeping around in town it reads maxed out. My mileage ran on average about 23-25 I havent totally figured it out yet. just got home, but if anyone has any pointers or places I need to check, Ill look for a burnt wire somewhere, but other than that any ideas??
