so i just put on my test pipe, with defouler and additional spacer....

threw a cel right away....

WTF any ideas??

 

First make sure its actually a cat inefficency code...

 

yea the cat code takes a while to actually throw the code. it is one of the last things the ecu tests.

 

02 sensor could be messed up if it threw a cel right away.

 

well it didnt throw it right away, maybe like after driving 20 minutes....

i know its a cat code...

 

Were you able to check it? I thought the same when I installed my DP and TP and the problem turned out to be the MAF sensor. So you can never be to sure about the problem until you check it.

 

checked it earlier today....

and it is a cat code..

any one with test pipes here throwing codes??

 

I had the same problem. I had MUFLEX make a test pipe for me here i NJ. I installed it when i got home and threw and 02 code. I installed 1 antifouler plug and still threw a code. I installed a second anti fouler and still threw a code. After installing 3 anti-fouler plugs, it had gone away.

MODS are: CAI, Test Pipe, Greddy TIC and an IVEY TUNE @ 10am tomorrow

 

I just put in the non fouler cel fix about 2 hours ago. I cleared the code and drove around for a while. I made it about 4 blocks the last time I cleared the code and before the fix. I made a lap of my town about 5 times as far as before and no code. Not to be a jerk... but you did do the cel fix correctly with the only one fouler drilled out and what not?

 

Huh. Did the anti fouler fix the problem. Your post ended in a bunch of run on sentences that made no sense to me. Could you please explain what you were trying to convey.

 

lol please do no insult my writing, i'm looking at yours and you ask a question but you type a period (.) instead of a question mark. Thats more confusing then my run on sentences.

Let me make this more clear since you dont understand.

I installed a test pipe, i installed the defouler (one drilled out and screwed into the other that is not drilled out) still throwing code.

Im going to try to install another defouler like maxmumboom and see what happends

 

what test pipe do you have? I have the UR test pipe and have never thrown a code.
