sounds like my problem on my 1g non turbo tell me if u figure out the problem

Swapping out the hacked MAS for a clean one from an 80k mile car fixed my problems beautifully. The car runs better now than it ever did with the damaged MAS. Balance shaft removal not-withstanding, the car runs smooth as silk now; accelerating, decelerating, cruising, boosting, doesnt matter, my GSX is running brilliantly. So, a new MAS might be something to look into.

Yeah that sounds like a Misfire and you engine cant retard enough. CHeck your plugs for sure , make sure the gap is right and that they arent dirty, Even if they look " okay" change them out with some NGK iridium anyways. I bet that will improve the symptoms. If the plugs are dirty or heavelly scorched then you probably jus thad your sensor go out.

This guy told me to check my plugs and wires...I didnt believe him at first either... turned out my wires were bad. If it doesn't work just wipe em off, put em back in the box, and take them back.... nothing to loose before spending 200 on the sensor...

To bad I didn't join sooner!!! I had the same problem with my car because i'm a girl my boyfriend didn't want to listen when I told him it was the wires!!! It's not fun trying to figure out what's wrong with the cars. I actually started crying today cause my cars acting up!!

I can not even begin to tell you how many posts I have where I have said


"Plugs and Wires"

I think with the exception of zero I was correct the rest of the times.

My ego is big.

And smack your boyfriend for me. and if your near Jersey and want to grab a drink let me know because any girl that knows what a spark plug WIRE is, is worth meeting!

Listen to this guy... he speaks the truth of wires and boyfriends, both deserving of replacement.

Ditto Addie... if your near PA anywhere hit me up for dinner and drinks.

can you guys help me. i have a 1995 gsx and when igo into boost it sputters. now the car can not go over 5000 rpms. no matter what i do it wont go over 5000 rpm. what should i do. the spark plugs are gapped properly and everything looks normal. i have no check engine light. what should i do

follow your engine codes. it's telling you the MAS or injectors are bad. If it was a spark issue it would just say, "Cylinder # misfire"

Boost leak. check your intercooler piping for loose connections, cracks, or holes.

Bet you he over boosted the stock BOV. Not too hard to do.

i have a hks bov and a tial wastegate

i have brand new 680 injectors

What else do you have?

yea with an external gate we definately need to know your mods. external gates aren't normally used with something small like a 16g

it has a manual boost controller, evo 3 16g turbo uprade, large fmic, full apexi exhaust system, walboro 255 fuel pump, maf translater gen 2.

my check engine light is on and all its telling me is that i have a bad o2 sensor

replace the one in the front on the o2 housing or check the wires. why are you using an external gate on an evo III?

now with the evo3 turbo could i just use the stock waste gate thats on the turbo or do i have to use an external waste gate

use the stocker. but have it ported to 34mm so you have better control and don't boost creep.

or you could use a bullseye stainless housing. better flow and already has the 34mm flapper. plus you never have to worry about it cracking cause its stainless.
