Help! Terrible MPG - - any ideas?
Hey guys, I'm new to the forum and also a new(ish) neon owner. I have a 2005 SXT 2.0L 4.0cyl neon.
The car was previously owned by a car rental company which I'm told is bad news because rental companies apparently have a history of not taking care of their vehicles. Anyway, I'm having terrible problems with my gas mileage. When I fill up I usually end up around 11.7 gallons, which here in atlanta where gas is $4+/gallon... that's not pretty. ESPECIALLY since I'm only getting around 220miles/tank.
I've done some research and know that replacing my air filter will help a good deal (now if only I could get the damn casing OFF of the air filter...any help regarding THAT would be nice too...) I've put fuel injection cleaner in as well as a new oil filter/change. I am going to get a tune up sometime next week. I guess what I'm asking is A)air filter help?? and B)what's you all's avg mpg? Any ideas other than new spark plugs/tune up/engine cleaning any ideas? similar problems?
Thanks a million guys !

Something is up with these stupid neons.
I've changed my filter, plugs, wires, oil, and i'm still getting ****ty mileage as well. I average around 25mpg on an ATX with 220 to a full tank in the city.
I'm thinking it's either an o2 sensor, iac, tps or all 3. Because believe me I have spent a good amount of money changing out what "should" have fixed it and DIDN'T. Save your money.

IowaNeon04 - I just called a local car repair shop (because no, i can't do it myself) and the guy on the phone laughed at me and told me my 02 sensor wouldn't have anything to do with my gas mileage. But, I think once I can figure out how the hell to get the casing of my air filter off and have that replaced I will give it a try. About how much was it to have it replaced? And I'm assuming that upstream is different than downstream and I would love to know the difference...

IT MOST CERTAINLY has a LOT to do with gas mileage... and yes, the upstream sensor is the one between the cat and head. I changed mine myself... it only takes a few minutes usually. If a chop has to change it for you, labor should be less than half an hour charge. I paid $25 for a Bosch sensor for mine. I'm not saying that everyone needs to run out and change theirs, in my case I really needed a new one due to a fouled old one.
