I recently put an exhuast and test pipes on my 05 350z and i got a CEL cause i didnt have CATs on it anymore so im guessing it was reading to rich but i solved the problem by buying 2 packs of (HELP! Spark Plug Non-Foulers) part # 42002 or 42009 eaither will work from Pep Boys or AutoZone they come in packs of 2 so youll have 4 total all i did was take 2 use a 1/2 drill bit to empt it out put the NON drilled ones into the test pipe then the DRILLED ones into the NON drilled ones then 02 sensor restarted the ECU an the light was gone cool an enxpensive way to fix the problem hope it helps some of you out

 

Or you could have had the dealership reprogram your ECU.

 

freak you're about 4 years too late to the party.... but I give you an A+ for effort.....

Welcome to the forums!

 

If a dealership "reprogrammed" your ecu to run fine without the cats... Illegal






OP must have EXTREMELY slow internet... I assume he pressed "submit" around 4 years ago and it just loaded.

 

This is only his first post. I bet his second post will be how he figured out how to lower his windows with his keyfob.

 

im sorry, but i cant understand what your wrote....

 

Come on now cut him some slack, he is only trying to help and thats part of what this forum is about. Welcome OP

 

HAHA i showed this local kid how to do that not long ago and his eyes lit up

 

im not 4 years late i just baught the car so im obviously just finding stuff out about it sorry to help you out! but its cool found this website just decided to make an account see what these cars are about

 

maybe you should have done a search and read about this prior to making the purchase

 

or maybe just search about after i purchase the car

 

Welcome.

 

Looking forward to his second post then!


Tim

You guys are sure being harsh. Freak is a newby and he was just trying to share some information he had just discovered. I give him an A+ for trying.
And congrats on the new car.
