Ive had my cats gutted and as usual....the "check engine soon" light is on. Any tricks about gettin it to go off? I heard you can buy dummy sensors but I dont know where to get em. Anything else work besides dummy sensors?

You will need to replace the sensor after the cat that reads post cat gasses

Hey I appreciate it! That definitely helps.

 

Or you can get a custom tune and have it programmed out.
