poor gas mileage

[moparfreak77]

Hey guys, was wondering why I am gettin so bad gas mileage. I have a 95 Cherokee

Country 4 dr 4x4, 4 L , auto, 97,000 kms. I am getting 23 on the highway(canadian figures). Before this one I had a 92 Sport and it would get 27,28 on the highway. same gears too...3.55

I have done the following-

Spark Plugs...wires i think are fine

Cap& Rotor

Fuel filter

Air filter

Oxygen sensor

Engine, tranny, transfer case, axle fluid have all been changed

I have put the same tires on this one, 30's. Same exhaust, Dynomax turbo cat back.

I have thought of thet cat being plugged but that usually means no power, I had that prob with my 92, felt like it had 100 hp [img]modules/phpBB_14/images/smiles/icon_confused.gif[/img] [addsig]

	Transfer Case Mounted behind and driven by the vehicle transmission, the transfer case transmits power to the front and rear driveshafts in 4WD Jeep vehicles and offers high and low range.

Don't know what the norm is for those, but you may try buying something like a Jacobs ignition system, they are supposed to qoute you garanteed milage increases or money back[addsig]
