o2 sensor

[s4983]

My camaro has about 70,000 miles on it, and I get only 17 mpg. I do both city and highway driving, and do not drive like an *** lol. Is it possible that I may need a new o2 sensor?

Re: o2 sensor

it could be alot of things. we will need a list of your mods. and it might be in your best interest to get a dyno done to see if your running rich or lean.

Re: o2 sensor

Like Kristen said, your mods will go into play on how good your mileage is. Get a new air filter, clean out the air box and put in some injector cleaner. When I first bought my car, doing that gave me about 3 MPG.

She's a 2000 3.8L, and everything is stock except for the Magnaflow catback exhaust.

I just ordered a K&N fipk.

...also bought some gumout fuel injector cleaner.

Hope this helps my gas mileage!

Re: o2 sensor

When I was getting low gas mileage I did a home tune-up and it helped out tremendously. Replace spark plugs, spark plug wires, fuel filter, oxygen sensors. Clean or replace air filter. Run some engine cleaner through it. Change oil and filter. Change differential fluid. While you're at it flush and fill the radiator. I've you have the original wires in there or non-performance ones I have found them to be a little flaky and not standing up well to the test of time. When I did this years ago I think 3 of the wires snapped off of the boot when I tried to pull them. Doing this got me back to the upper 20's for mpg.

you dont need a dyno done to see if your running rich or lean.

listen to this guy. if i were you id do plugs and wires 1st, it can really make a difference. you dont have to get special wires or plugs. oem replacements will cost about 60 bucks total for plugs and wires. while you have to old plugs out look and see if there black your running rich, if there white your running lean. if you want you cqan get high performance stuff but not nessecary. fuel filter is a easy one to do to and only cost about 10 bucks, gaurantee you notice the throttle response. you could probably use o2 sensors but id hold off on them until you get there other things done.

i always keep up on these thing meticulously, im average about 25 city easy. thats not even trying to get the most out of it either.
