Mister 2 running way tooo rich

[430hpToy]

Anyone have any good advice on how to lean out my AF mixture?

Here's a list of mods to get a rough idea of what's goin on...

JDM 3sgte motor
bored.040 over
K&N Filter adapter
Adjustable Cam gears
Fuel Cut Defenser
eliminated cats
removed TVIS
and i think that's about it...

haven't touched the Cam Gears yet... still set from the Factory!

MAF/AFM? bad FPR?

How do you know it's running rich?
I agree w/ aosmith, it's most likely a mechanical prob or sensor input prob.
Fix that instead of trying to lean out the mixture.

when i was running too rich i changed my spark plugs(NGK Copper 6097) and gapped them at .028 it seemed to solve the problem for me...

mine are gapped at .036

is that too wide?

.028 seems prety close!

i'm also running the NGK BKR6E plugs

should i use a different plug?

im using NGK Copper BKR7E 6097... i gap them at .028 cause i run a higher boost than stock... most people just use .03 but i like them at .028 my car idles and runs just the way i want it too now... go to mr2 controls and read about it there... they have really good info on the site...

.036 is too wide even for stock!
I'm mostly stock running 15psi and gapped at .030 NGK's coppers with 205rwhp. NGK's are good....you should go .030 or even .028 depending on how much boost are you running.

yea, i'm running about 15-16 psi... i just gapped them to .030 today! thinkin about goin a lil closer.

still runnin rich as hell though!

could it be the O2 sensor?
i'm also runnin the JDM ECU w/ the motor, i normally run 94 octane in it... if i have a couple extra bucks on me i'll run 100 octane (Mister 2 loves 100 octane!!!)
^not sure if that will help any!^
