Gas Mileage Options

[o0black0o]

I put some 3-2-1 headers on bout 2 weeks ago. We also removed cat and placed a gutted one. I would of assumed i would be getting better gas mileage. but Im accually down 100 miles per tank. We did reset the ECU, via pulling the battery cable for 10 minutes. Shouldn't I get better mileage by at least like 1mpg or something or is this common? I have the 7afe so It might differ from the 5s.

Also I dono if this might be a cause but, I installed an auto meter A/F raito gauge its not reading. I currently have no Check Engine Light. But Since my light isn't on my O2 Sesor should be fine. Its only abour 3 months old. Am i right?

FallenHero: I installed the A/F Meter and the 4-2-1 header the same day. So I have not a clue. I just changed my spark plugs, took a drive down to the store, suddenly the Meter started to work somewhat. Light was on yet it was boucing like crazy from lean to rich and back and forwth.

Bitter: Yes I blieve I did. 2 Wire Heated Sensor, connected to the white wire on the O2. Ground and Power.

Batman: Thats not entirely true. Unless your just talking about headers. Ex: CAI
