Fuel filter, o2 sensors, plugs & wires have less than 10,000 miles on them. The K&N cone on my CAI could use a cleaning, but that alone would not cause such a crappy mpg.

Any ideas why I am getting such crappy mpg?

 

i hope you're talking 13-14 hwy miles and not 13-14 city miles. b/c 13-14 city isnt crappy, just less than perfect i suppose. I get 10mpg city, now thats crappy

 

Man I get 25-26 highway miles and about 16-17 city miles with my set up...

All of this will get cut in half after the cam install

 

between 14-16mpg city here. Highway I easily see 20mpg

 

i was getting 17mpg city and 25mpg highway with my 2.73s, now I get 15mpg around town, but haven't really taken a highway trip yet.

 

Have you ever had your fuel injectors cleaned?

 

No. and the car only has a few bolt ons with 3.23 gears

Last tank I got 194 miles on it. Only one time I went WOT and it was only for a second.

 

I get about 220 miles to a full tank of gas/ highway & city combined and thats with me doing a lot of open throttle driving

 

How the hell are you only getting 10mpg in the city.

 

im only getting 13-14 city miles also... how do you clean your fuel injectors... buy some bottled stuff from autozone?

 

I have no idea why i only get 10mpg. if i knew i'd fix it. new plugs, wires, pcv, fuel filter, coil, different MAF, no codes. only thing i can figure is either opti or clog in the exhaust somewhere as she does also seem to be down on power a little bit. any suggestions would be appreciated.

 

I don't know man... I would check it out though. Mine gets that even with the gears, cam, TC, etc. The little turbo rice cars look better every time I hit the gas pump.

 

Not all cities are created equal, example State College:

Start car up, idle at stop light. Drive 30 feet, stop, drive block and a half at 15-20 mph, stop, drive 1/2 block, sit and wait in friday football traffic, drive a block, stop, cross atherton, drive 4 blocks at 20 mph, turn right for one block, idle while you pic up your beer, and reverse the above process for the return trip!

That combined with my roomate driving ~1mi daily to work netted me 10-11 mpg. There is nothing more than 1/2 throttle if that in those trips. The car does fine on the highway and in 'normal' city driving, but short slow trips kill mpg.

I just rebuilt my engine... I'm sure the 133k mile injectors would like to be able to keep up with it. I'd like to know how to clean them too.

I get 9mpg in the city... I'd kill for 13.
