I only have 1 o2 sensor, so ill just replace it and hopefully that fixes the problem![]()
I don't have a rear o2 It isn't needed on the pre01 cars but i'm sure it's probably needed on the 01+ ones.
Yea I replaced the o2, cleaned the maf, replaced air filter . Still 15 mpg -_-

Update :
Had a super bad ypipe leak typical pacesetter problems, testing the mpg as we speak, will update soon, if this didn't fix it I'm going to be heated lol

Here's a simple idea for you too. What t-stat are you running. If its a 160* get rid of it and go back stock. Or just change it for good measure. If your car's not getting upto operating temp you'll burn more fuel.
Honestly, we have to see the tune that's on the car and what the DTC is to pass judgement. If the car is in otherwise good working order... i.e. headers don't leak, no vacuum leaks, then I would cover maintenance basics. If the plugs and wires are original then get some new delco wires and Autolite 104's and set the gap to .055. If the tune is anything like ZZP's, the power enrich TPS enable could be set really low like 30% across the board. I raised my PE TPS enable back up to stock because it was going in to PE way too often when it was unnecessary.
You can compensate for that via the TPS adder.
Hey Snazzy do you still have your rear o2 sensor? If you don't its prob running cat diagnostic test all the time which would explain the low mpg...my 04 comp g is getting around 19 in town but I also have PE set at 30% so I need to raise that back up because it goes into PE real easy with the 3.29 gears
Gas mpg is. Still bad, actually a little worse than before with the exhaust all sealed up now, i do not Still have a rear o2

Put a rear o2 sensor back into that beast and I am sure your mpg will increase
Dark horizon yes I did for about a half hour
