:help: 130k miles on the stock ones, just got a set of Kooks headers and the car is acting like a raging bitch. Believed to be b/c of the 02 sensors.

Don't know what acting like a raging bitch bitch means but you should havit tuned after a header install.

From what i'v heard, a tune wouldnt be causing it to act like this. bad 02 sensors would though.

horist

can you elaborate on what "acting like a raging bitch" means?

Also are you setting an SES light?
Do you have access to a scanner or a friend with a scanner ?

If the O2s are slow it will generally set an insufficient switching code... narrowband O2s run 70+ each, so i'd suggest more info and research rather than potentially throwing the money away

Iv had the SES light on for some 50k+ miles. I'll see if i can get it checked today again. If I did go w/ 02 sensors, what would be a good brand? and id need extensions

Its bucking when normal driving. Once i get it up to cruisin speed, it starts kinda kickin and acting like it wants to die, but it never does

Bosch 13111 They have the additonal length needed on the wires, no extentions needed.

Tuning is not really needed after a header install. helpful yes, needed no.

definately.

You need to be more descriptive in your post. What year car/mods. Someone near you might can tune out the codes that are causing your SES pretty cheap if they new what you had and what you needed done.

Bosch 13111 o2's and you wont need extensions. And with 130k, I would say change them even if that wasnt the problem.

EDIT: I see Brad beat me to the answer.

What is with everyone saying you need a tune for headers?

RMR JAM

I guess I shouldnt have said "definately". But changing anything that could affect the volume of air going through your engine can affect your fuel trims and a little tuning can get the most out of your mods. That being said. I dont wanna second guess someone with 6000 posts. You will need a tuner to delete the codes for your SES lights though even if they dont "tune" your car.

Post count means nothing, take that with a grain of salt.

Yes tuning is always the best thing to do no doubt, its just some people get misled when they hear these things, especially about headers. Everyone that has a problem how their car runs after headers is told by people on this site to just get a tune when 95% of the time the real problem is something else such as loose plug wires, cracked plug ceramic, or failed O2 sensors. Headers alone will not cause your car to run all jacked up and a tune will not fix it.

Yeah all a good header install will do it throw your fuel trims around little bit, which most likely wont even be noticed unless you are scanning.

Thank you Iv mentioned this several times and most of the time, the response is "Oh, you need to get it tuned!". Nooooooo There is something else amiss besides the tune.

I went to AutoZone and bought the Bosch O.E. o2 sensors. Kooks sent me extensions w/ the headers, but I'm not sure if they're long enough for these Bosch o2s. We'll see.

Just curious, why wouldnt I need extensions w/ the 13111s? I believe I bought the 13444s or something (It listed as the Bosch O.E. style)

RMR JAM

the bosch 13111's have longer wires on them. They are at least 18" longer, maybe more.

DANSBIRD

HMmm thanks. I'll take these back

DANSBIRD

Are there any modifications needed w/ the 13111s? or just plug them right in

RMR JAM

iTrader: (4)

no mods necessary

DANSBIRD

The headers came w/ extensions, I THINK. Perhaps the 13444s that I bought plug into the extensions :hmm:
