Mark VIII gas mileage

[LORENZOCHICAGOLSC]

Drove to Lake Geneva from Chicago, averaged 15.1 M.P.G. What needs to be replaced to make this better???

 

[MonsterMark]

Spark Plugs, Fuel Filter and O2 sensors.

Yep!

Dont forget the air filter And cleaning the wire in the mass air. I picked up 3 mpg just by doing that. I currently get 16-18 around town and 25 on the high way with the a/c on

I've been getting close to 16 city and 27 highway lately. I recently had a jump in mileage. Probably due to replacing worn front suspension parts. I also replaced my mufflers with 3" tips, but don't know if that did anything. I have also replaced air/fuel filters, and plug wires. Yeah try cleaning your MAF sensor like poney said. It takes about 5 minutes.

Just shoot cleaner up the air intake?

 

[rmac694203]

No. Take the air box off the car and remove the filter. Look down into the air box and you'll see the 2 wires for the MAF. Just shoot electrical connection cleaner on those wires for a min. and let them dry. I think Geno said you can use Gumcutter 2+2 or whatever as well.

i think i might need new plug wires, has scorch marks on 1 or 2 of them. my car was running poorly, choked, hesitated. you name it. i cleaned it with carb cleaner like you guys were saying,"worked well". before i had a friend change my fuel filter, it was solid. i keep getting a fuel to lean code even after both things done. fuel pump maybe? but anyway i get about 16mpg in town and accoding to my message center........anywhere from average of 30.5 or so highway.....or is it wrong maybe? lol

before something bad happens, i suggest you check that your friend didnt put the new fuel filter in backwards...

I took the airbox out, and looked down the big tube, and there are no wires.

I also have a '97, so I don't know if it is different for Gen II's.

 

[Calabrio]

On the top half of the box retaining the air filter- inside you'll see the MAS. Inside it you see a little tube with two very tiny little wires running across it.

I went from 17 to 19.4 in town average. I cleaned the K&N and mass air meter.
