Update on gas milage improvements....

Well i posted awhile back about decreasing gas milage, it was the concensous that it was the O2 sensors. Well this is a 2000 it has 4 O2 sensors, so 300 bucks later I replaced all 4. Well after about a month of driving in different conditions, im averaging about 17 around town up from 16. In the mountains 18 up from 16, and on the highway no mountain driving, dunno havent made one of those trips. Im guesstimating about 20, use to be 22hwy, 18cty, 20 mtn, but the tires and lift have taken some off the milage. so you can do the math, but it was worth the 300. Next up is exhaust free flow cat and muffler. Take another month of driving see where its at then do intake on it, filter and throttle body spacer. Drive another month and see where its at. Hope to gain a 2-3 points in town, maybe only get 1-2, town driving sucks with these things. Hoping for another 4points on the highway, that seems to be the biggest area for improvement.
