I searched and im pretty sure the reason my SES light just came on tonight [1300 mi. appx.] is because im running no cat and i DO NOT have a o2 simulator? is my assumption correct? I just installed a Tanabe Concept G Blue TBE and am running a test pipe, and i put the o2 sensor in the catback [obviously there was only that hole]. I have a o6 ix.

This is my only mod.....my question is, do you think it might be anything else given this is my only mod thus far, and is it hurting my car? Thank you in advance!! also it didn't come on after i installed it.....i 've had it on for a few days now......THANK YOU !!!!!

 

Go to autozone and have them read the code for free.
and yes most likely it's the "Your Cat is dead" code :P

 

hahahaha ok so if the code is on because im running no cat, than what? I have to buy a o2 simulator? thanks again!

 

either u buy an o2 sim or u can buy 2 spark plug antifoulers and do the mechanical fix.
