bad gas mileage
 

it kinda seems like im getting crappyier gas milleage than i used to does anyone know of anyways to help me because all my money pretty much goes to gas and it sucks

o2 sensor? new spark plugs? tire pressure?

Full tune-up is the only eliminator for bad gas mileage, if it makes you feel any better my N/A gets 27-29mpg (TII gets about 8, heh) :D I've got the following that are new:
Fuel filter
Oil filter
fluids
spark plugs
o2 sensor
spark plug wires
extra grounds
some hella luck

:)

fuel filter?

alright i'll try those. thanks guys

Just do a basic tune up if you haven't done so .
Also, check your O2 sensor.

shift blow 3 k, an try an keep her in closed loop. i get about 27-28 highway on my NA, and i usually average 25 mixed. when i had my ports wired open though my mileage went to crap.

i get about 330kms's to a tank. thats about 19liters per 100ks i dont know how to convert it to mpg:D

Why is it that the rest of the world is on metric and the US is not? :confused:
There seems to be no change in the future.
I'd rather use metric.

The tune up would probably be your best bet. If you have over 60K miles, you should also consider removing and having the injectors professionally cleaned.

Also make sure your ferio E-fan is not on while driving highway will help as well. If it does not freewheel properly it could add a significant drag to the car at freeway speeds. As I recall those fans were designed to pull air sideways, rather than straight through.

It is very easy to wire a relay off of the 5th gear/over the top switch to disconnect the fan when ever you are in 5th gear.

With a Turbo, its hard not to love the boost, I think its best to save the boost for when you really want it...so as has been mentioned, shift below 3k when your not needing it, also I do alot of city driving, so I look ahead to see if I am going to get a light or not, & coast & take it out of gear if I am not going to get through a light...
Or when I get on the highway, if I am not in a huge hurry, I will get into 5th gear quickly without getting up into the high revs...makes a huge dif!
Good luck/skill!

SonicRAT, 27-29mpg?!?! That's awesome!!! Mine gets like 16 in the city... I need to do something eh?

No 16 in the city is right on the EPA rated the RX-7 for 17 city and 24 highway.
I on the other hand am only getting 12 in the city but I just learned that my leading coil was not working.
So I hope that my car will get closer to 17 with all 4 plugs firing.
I figure if you are getting 15 to 17 in town with a N/A than you have nothing to worry about the rotary engine is not known to be fuel efficient.
;)

Ok cool, thats what I thought -- I just couldn't see how he was getting 27-29.... that's like a toyota corolla gas mileage!

my car before had a gas leak it was like that comercial where the guy reved his car and watched the needle drop hahaha

well im pretty sure its not coming on because when i pull over into a gas station it takes about 10 or 15 seconds then it comes on but does that meen its not on while driving??

I get 29 highway, and 23 city.

on which of your 7s sonicrat? And one more thing how??!?!
