Thread: im tired of this stupid gas milage!!!

Right now im getting around 260-280 Miles/tank. I was getting close to 400 miles/tank. I have no idea what it could be. I have replaced the plugs and wires, have open cone filter, replaced the Idle air control sensor (when i first got it), new fuel filter, new tires and alightnment, new filler neck for gas tank. and seafoam in the cylinders and gas but not the crank case.

now. I had an SES light on. codes were for an o2 sensor, iat, coolant temp, and misfire. but the SES light went of and has stayed off. Should I replace all of these?
Another question. The vacuume kit from zzp, does it come with the plactic fittings, or do you just push on the line (on the metal fitting on like the TB)?

Gas mileage should go a down a little in the winter, but a bad o2 sensor is going to make it run rich/lean possibly causing the misfires. Replace the o2 and iat sensors and clean the coolant temp sensor or replace it. See what happens then.

ooooo....missed the question there. just becuase those codes pop up, doesnt mean the stuff is actually bad. It may be a vacuume leak which will cause multiple codes to go off.

i was asking if i should replace them sensors even thought the ses light is already off. and i would like some info on the zzp vacuume kit...pretty please lol

THere would be no need to replace them if they aren't broken. Find you vac leak, cause its probably whats causing your starting issues as well.

well....i probably should have said it. but i have been getting bad gas milage the whole summer/fall.
