Getting bad gas mileage I need suggestion

 

What do you consider bad? Are you lifted with bigger tires on stock gears?

 

Yea 4.5 lift and 31 inch tires... but its gettin worse

 

What is it?

 

Cracks in your manifold? Clogged cat? Tired o2 sensor? Old fuel filter? Injectors need some cleaner through the tank? Have a fuel leak somewhere? Have a roof rack? Heavy on the gas and brakes? Need some Seafoam through the vacuum line from the brake booster to the manifold? Air filter need replacing? Throttle body need cleaning?

This list can keep going man. What have you done so far?

 

Sea foam, injector cleaner, new map sensor, new cap rotor, plugs, wires, never cleaned throttle body no cracks in manifold no roof rack

 

And clean air filter

 

Check for codes even if lights not on see if any sensors are acting up.

 

I'll go up to auto zone and have them see

 

worst thing can happen you find out nothing wrong

 

But it's progressively getting worse and it idles rough to

 

How does your entire exhaust look? Cracks, leaks, or rusted/clogged components?

 

lift and tires does that. I get about 8 mpg and im on 2" and 31s.

 

Cracks on exhaust and when I take off it lugs some times and pops in throttle body then takes off

 

Well in that case, definitely get it scanned to see if there are stored codes
