stock right now, only muffler and coilovers. any way of testing an o2 sensor and checking if its good or not.
bumper isnt black. the muffler has black on the inside of the tip. ( came pretty black but tryied to clean off most of it ) dunno weather its rich from the preivious owner or if its mine,
havnt checked the timing but when i bought the car i think the previus owner was messing around with the cam gear / timing belt. should take a look at it. havnt used a test light before tho. could borrow one

Most common causes of bad fuel economy are poor choice of engine mods, bad or improperly inflated tires, O2 sensor, or some other problem putting the ECU in limp mode. Does your exhaust output black smoke (stains on your rear bumper)? Did you make any change to the injectors or fpr? Do you have a chipped ECU?
Have you checked the ignition timing?
