Hello, having a issue with my rig, it is using ALOT of fuel. I was expecting 11-13mpg with 33's. But I got 6mpg. Constantly.
Specs are
33x12.5r15 tires
4" lift
arb bull bar
No engine light or rough running.
I have done
new spark plugs
new plug wires
new cap and rotor
new air filter
egr and smog delete
valve adjustment
Seized caliper(replaced)
new oil in everything
re built a440f trans with new torque converter.
What do I do next!? It has a little power but nothing above or below average. I am running 87 octane in the tank. I have run 3 cans of injector cleaner though it over the past 5 months. Could the cat converters be pooched? I have a lot of suit on the tail pipe too. Could leaning out the afm help? I don't know much about the 3fe so what advice you have is helpful
A lot of people have made threads on bad mileage but they are getting 8-9mpg, mine is at 6 and the engine seems to run great with no stumble or hickup.
HELP ME! I am spending a fortune on gas! A tank only lasts 200km/120mi!!!!!!!!!!!!! I am not hard on it either I cruze at 100km/h -60mph no hard starts or hard acceleration.
