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)?
