97 Hardbody 4x4 Bad Gas Mileage??
I just bought a used 97 hardbody 4x4 4cyl 5spd. It has only 79kmi on it. It is a regular cab truck. I drive with my tailgate down EVERYWHERE! I am only getting 14mpg. I replaced my front 02 with a Bosch new unit cause it was throwing a CEL. I also just did EVAP purge valve and canister for same reason. The plugs look a little white, im not sure why. What octane gas should i be running?? I just changed all fluids in the truck to AMSOIL fully synthetic and no change. I also just cut the A/C belt off cause its winter and i dont use it anyway. I have a new belt for summer (needed to be replaced anyway). The truck doesnt misfire or anything like that seems to be really smooth driving, and yes the hubs are unlocked. The tires are 265/75/15 and should be 235/75/15. will this make that much of a difference? My new 30x9.50x15 all terrains are on backorder so i have to wait till they come in. What else should i be looking for to improve gas mileage?? I have run fule injector cleaner through it to no avail. Please help I am gettin pissed and I dont wanna sell it but I'll go back to Honda if it continues i dont really need a truck.
