i pulled a code today and it said i needed to replace my first 1st o2 sensor. than the guy that pulled my code for me said its my coilovers. i was like ummm i really doubt that. he still insisted it was my coilovers.

i know for a fact its not the coilovers. is the egg smell coming from a bad o2 sensor? thanks

 

Are you using a catalytic converter? If you are smelling a sulfur like odor, you most likely are not running a cat. or your cat. is going bad....

 

Take it to a real mechanic who knows what the hell he's doing. Coilovers.... psh

 

Sounds like a cat converter issue.

 

o ok thanks guys!

o ya my code was pulled for free from autozone. their not real mechanics anyway..haha.

 

Coilovers? Maybe he ment CoilPACKS? they control the spark to your spark plugs. You have two, and each one contols 2 cylinders.

What I would do, if you wanna do it yourself and not bring it to a shop is.

Throw some injector cleaner in there, clean up the injectors and o2 sensors (sometimes works, sometimes is a temp fix) I start with this when I'm not the shop scan tool and get an O2 code. If that doesent work, replace the o2 sensor.
Bank1 bank 2 refer to what cylinder head its on, so we have a 4 cyl so it would be bank 1, the 2nd number refers to what o2 sensor itself is. 1 is the 1st one, in the manifold, 2 is the one after the cat converter, it can also be called a "cat efficianty sensor". If that doesent work, inspect your spark plugs, see if they look okie. Actually, you know what, do that 1st. lol

And if all else fails, replace the coilpacks and the two wires.

BTW after you perform each task, dissconnect the battery for a lil while- cheapo way of resetting the light.

goodluck ^_^

 

deffinitly the cat i had the same problem untill i got a high flow.

Do you happen to remember the code you were throwing? Was it P0135 by chance?

 

i dont remember man but i remember changing the spark plugs and it stopped smelling.

 

turbo with cats? It's robbing horsepower!

 

im running straight pipes, but i took off the turbo kit for some warranty purposes.

i agree who runs turbo kits with cats haha jk

 

I have a catted TBE. You don't lose nearly as much power as people think and in all likeliness, you don't lose any at all. I'm pretty sure our local tuner/subaru god did some comparisons between catted and catless and unless you go with a massive turbo, the difference is so minor you couldn't possibly notice it.

 

i agree removing the cat doesnt make a difference but 5whp is still a good gain in my opinion without the cat. it also helps with spool too.

 

There's no proof that you gain 5whp though, people have just the assumption that a cat is a restriction thus they need to get rid of it. I suspect that the flow difference between a test pipe and high flow cat isn't enough to justify the noise, smell and legality issues that come with a catless setup.
