question? i have ls auto teg and 10lbs and it is not as fast as it should be and it does not have any boost leaks my o2 sensor on the exhaust is not hooked up will hooking this up make a big diff or will it not matter?

do you have a boost gauge? and the exhaust leak will help im guessing your not really running 10 lbs

IFyour O2 sensor isn't hooked up you will have all kinds of problems, the ECU can't do it's job without an O2 sensor signal..

do you have the wire color to the o2 sensor fabrik i the pins came out of the harness an i never hooked it up

HOLY SHIT DUDE! No wonder your car isn't running well, you're probably running a 9:1 AFR. Your car is undoubtedly in limp mode, which just lets it dump asstons of fuel into the mixture to prevent damage. You MUST get a new O2 right now. This will fix a lot of problems. Then get it tuned to make sure you don't have any real problems with leaning out.

Good luck.

i have the o2 sensor on the manifold hooked up just not the one at the end of the down pipe will that make that big of a diff? merf?

Do you have an OBD1 or OBD2 ECU?

i found the o2 colors and i have an 0bd2 it is a 98 i used all data to find it

Hmmm...I don't think so, but it surely can't be helping. I was under the impression it was your one and only O2 not hooked up.

Someone who has dealt with OBD Hondas has to chirp in now, I'm pretty much out of my league on the specifics of the two sensors.
