Guys,

Need help. I have istalled the CEL fix that I bought from Gruppe-s. I have an Helix downpipe, stock cat and Greddy Ti-c. I have gone to autozone and it showed 02 sensor...

 

You have to reset the check engine light.

 

I did that twice already..... Unplugged the negative wire overnight...

 

why are you getting that cel with the stock cat?

 

yea what he said

 

must be wired up wrong???? You shouldn't even need a cel fix on the stock cat. Whether you have a dp/cat back or not, if the stock cat is in place, you shouldn't need the cel fix.

 

I was asking the same question...

 

but even with the cel fix it shudnt go off because it only triggers when there is too much exhuast flowing through it not how little rite??

 

I thought the electronic cel fix didn't work on the IX's just the VIII's. Try the spark plug antifouler mod in the how to section-easy fix and its under $3.

 

ooohhh he has the electronic one

 

Why not get the drilled out spark plug defoulers like everyone else.I have a Perrin 3" HFC and the defoulers and have had the HFC on my car for about 4 months now and no CEL.

 

since you have a stock cat why not try removing the cel fix. what is the condition of your cat?

 

I did not have a CEL fix at first and it sill lit up... I only have 6000 miles.

 

Did you buy the one under "test pipes and cats" off of gruppe's site?

If you did you don't need it with the stock cat, using it with the stock CAT still in place will throw a CEL also because you have too LITTLE flow instead of too MUCH. Also note this is the mechanical fix NOT the electronic one. In this case your still relying on your actual O2 sensor to function. However you stated that you got a CEL before the "fix" but was it on before or after you put the rest of the exhaust on? Do you think you damaged it when taking it out/putting it in? Did you even take it out being you still have the stocker?
