I get about 275+ to a tank and i am no way near tryin to convserve gas i want to get to where im goin as quick as i can and beating as many people as i can if i drove conservatively i think id be up around 285+

have u ran a tank of premium thru it lately to clean everythin? id try that and tire pressure and a thru the tank injector cleaner

 

I hit 170 miles at 'round half tank, I usually refill at half or quarter. Mileage high twenties on an MTX and I *WISH* I could get thirties and above, since on paper EPA nums are 29/41.

 

Mine dont have bad mileage.... the problem with me filling my gas tank up every couple of days is that i drive everywhere!!!! for otehr people... I hate being the only one with the car. Granted they pay me for the gas but that's not the point.

The point is that im putting 500 miles a week on the car and it will soon take its toll. i will get her tuned up again in january after she sits for a couple weeks without being driven. Im leaving the country on a vacation and my baby deserves a break.

I rarely use A/C. If i do, it is always on 1 or 2 power and never on long. 02 neons have a sunroof (mine does at least) so I crack it alittle and open the vents but leave the compressor off so the outflow from the sunroof pulls air through the vents. Works fine on cool days and even on hot days but, you you cant stand the heat, get out of the kitchen.

You need to take it to a dealer who has someone who knows what they are looking at on the DRB III. A downsream O2 has NOTHING to do with fuel mixture. A correctly operating downstream O2 should switch approx 1 time for every 6 swiches of a upstream. It is there only to monitor the converters efficency. We are turning the exhaust into O2 and H2O during the process. That is why it is called a CONVERTER. We will havea O2 withslower switch rates. I have found many problem that do not set a CEL on. I have found maps that show barometric pressure to be 28.8 and truely be 29.5. The pcm doesn't know it is not. It updates on start up and WOT, or the coolant shows to be 180* and be 210*(colder engine requires more fuel, that is how you benefit by "tricking" the pcm into thinking it is colder when it is not). All of these will cause the fuel to be inaccurate. This can beEASILY detected by the fuel adaptives, if you know how to read them. On Chrysler vehicle a TJ may require the adaptives to be 40% +/- (long term and short term combined) before it turns on a light and a neon be 50% +/- to turn onlight (not accurate numbers just example). All vehicles have different limits. It changes from update to update and year to year. Just flashed a Dakota PCM for a Lean code set and does not have a lean condition. The program has higher limits before setting a lean code. Iam a Technician not a mechanic. I do 75% of the drivability work at my dealership (Prebul Automotive Dodge, Jeep, Chrysler). If you are close to Chattanooga, TN I would be happy to look at yours. PM me and we will get together.
