Any CEL?

come on someone i need some help

 

check two things, take a voltmeter to the o2 sensor, the voltage should jump up and down. Next check out your IAT sensor on your intake manifold, this caused my car to run a bit rich.

it can be something stupid such as spark plugs, wires, dizzy cap & rotor or dirty *** injectors.

and check for codes

Just changed my plugs and wire and put some Lucas Injector cleaner into my last tank of gas and my mileage has increased by a lot. I'll be planning on doing cap and rotor next.

any chance your mileage went down because your foot got heavier?
