What a list of things I should change to increase my mpg. Right now I'm getting like 12mpg if that, on my '90 N/A.
What should I change to improve my mpg?

 

full tune up

 

stop redlining it :P

 

heh , I'm not redlining it. Matter a fact i try to keep it under 4k.

 

Spark plugs, plug wires, and air filter would be a good start.

 

yeah a good service tuneup should do wonders. you should be getting 20+

 

get rid of the auto... lol

Edit: My mpg doubled when i went to a 5spd. My city mpg is around 17

 

I got a 5 speed .....

 

Set your TPS, make sure you ahve good catalytic converters, clean spark plugs. have your fuel injectors cleaned and calibrated, change your air filter. Check for vacuum leaks. Change your oil. etc.

 

Two more things that should give you more MPG.

Crane Cams Hi-6 digital ignition gave me a slightly better MPG. I was avg around 15-16 went up to 17-18 or so.

SAFC. Leans out your uber rich FC and should give you a couple/few more mpg as well as mo powah.

 

That will add mpg, but it will by no way fix his problem.

 

yea im gonna git my injectors cleaned and go for an safc

 

New O2 sensor might help as well right?

 

o2 sensor will only affect freeway mileage because it works only in closed loop mode or cruising speeds.

 

Change the air filter if it needs it or switch to a cone.

 

scrap those clogged cats

 

Buy and tune an SAFC2

 

sell it and get a civic....with these gas prices....civic is ur best bet
