I bought new a 1996 Bronco, XL, 5 liter/302 and have about 130,000 miles. I WILL NEVER SELL IT and if you drive a Bronco that never let you down you'd feel the same. I just got thru replacing the fuel pump, radiator, entire front brakes system - calipers, rotors, pads, say $2000 total. Truck is in real good shape, so now I am wondering why I only get about 12 mpg on C470 doing 70 to 75 mph. In the city maybe 10 mpg. So I looked into 02 sensors.
Question - do you have to replace sensors when they fail or every 100k miles? Dealer says replace when they fail.
Question - can a sensor with 100k plus miles on it give bad data back to the computer and thereby affect mileage and run rich?
Question - won't a sensor that is not performing as it should get the check engine light to come on?
Question - dumb question BUT I can get Boush 02 sensors, and there are 3 of them total, for less than $40 each, but dealer charges $122 each. I cross referenced the Bausch number with the OEM number and they match so I got the right parts. For a 300% markup, am I overlooking something ? or are the dealers just that greedy?
Question - is there a way to check trouble codes by just using a paper clip and counting flashes? I did that on my old Camaro. You count the flashes and than look up the problem.
Question - any after market items or other things I can do to improve gas mileage? Major tune-up done last year. I spend about $4000 a year on gas.
Question - last one. I got Yoko Geolander tires last year. Best tire I ever had on a truck. I kept the factory wheels but went up one size. That won't make a noticable difference in mileage will it ?
