ok i have a 2007 5 speed tc and i have 4-1 headers and a injen CAI soo i put that all on and i put the anti foulor and my CEL came on and i dont no what to do i dont no if i need to move the O2 sencer

 

you need to find out what code the ECU has thrown.

 

the fault code could be anything

key word is " OBD2 scanner "

availalble at your local auto parts store.

the OBD port is right underneath the driver knee airbag.

Connect -> Read -> Diagnose/fix -> Delete

 

i got got the car scanned and they said that it has somthing to do with the calatic convter and the O2 sencer

 

what is the exact fault code?

 

they said somthing to do with the conrevter i will get it scannd again and the i will tell you

 

That scanner, how much does it cots and its it just a rental piece or do you have to buy it.

 

scangauge II is a great scanner to have, can be bought for about 165 - gives about 15 different gauges, and the ability to track mileage, miles to empty etc. you also get to scan the engine codes, and the snapshot of the sensor readings at the time the code thru.

but yes, the EXACT code is integral to the solution.

 

Thanks, my cel came on about 300-400 miles after I got my exhuast finished, with OBX header, S-pipe w/ antifouler, 20" resonator and a custom catback exhuast.
