ok so over this past year i put a fujita cold air intake, magna flow exhaust, and vibrant headers in my car. The problem is my check engine light wont go off and when i brought it in they said that the codes are coming up that there is no warm up cat and about 10 codes in all showed up.. i need to know what i did wrong, what to do next, and what actually is my best bet. i need to pass inspection in three weeks and im really in a bind.. any advice is very much appreciated, thanks guys.

 

sorry to say you did nothing wrong, that is a common problem when people install headers on there 3, the weird part is the vibrant setup is supposed to eliminate that chance so unless you cracked that header or it was cracked you should call up vibrant to see whats up, the only other option you have to revert back to the stock header.

 

ok i figured thats what i had to do.. maybe when i installed the o2 sensor it wasnt done right.. im sure it was though. guessing im gunna have to do the old switcharoo and get it inspected that way.. thanks alot bro.

 

np man good luck and hope to see you around more

 

What about the header/O2 anti-clog trick?
Using a spacer made from an old spark plug to keep the O2 out of the direct line-of-fire from the exhaust gas itself. I do not have a header, but have read that this trick works to eliminate CEL's when using one.
It might be true, it might not. Can anyone verify this claim or add to it?

 

well like i said i didnt use any tricks and my cel never came on and again i have the obx header, ive talked to the owner of protegegarage about it before i even bought the header and he said its a 50/50 chance on any of the tricks used to eliminate the cel, in short OBDII is really trying to take the fun out of everything and a little bit of Mazda being **** about keeping the ECU on lock down, its why im looking for an OBDI car
