01 durango. getting horrible mpg around 6mpg
hello everyone. hopefully someone can help me I've had this one for about 2 years never got the mileage it should but just dealt with it since it was no codes. but now its too bad to ignore it have copper plug, air filter, crank sensor cam sensor upsteam 02 my model only has 2 one before and one after the cat. ive ran injector cleaner before the recent new 02 sensor. its idles normal drives normal starts fine. im lost as to why i'm getting such bad mpg its has 265-75-16s im thinking.. but even with those tires everyones getting 11 to 17 mpg city my odometer is pretty right on. I had the cat tested its not clogged. my clutch fan seems loud but think its normal with these and it runs normal temp. i have not checked my compression yet

Hello,
Hopefully this may help.
I replaced cap, rotors, plugs, wires, IAC sensor and had terrible mileage.
I later learned the electronics must be reset after any changes to bang, suck, blow.
Try disconnecting the negative battery terminal, then put the key in the ignition and turn to the crank position for 5-10 seconds.
This clears the capacitors and allows the engine to "relearn" how to manage all the new parts.
This made a major difference in power, shifting and mileage for me.
Best,
Heekma
