I took my car to the dealership Saturday because the car was not running right. They call me today and tell me the problem is because I am not running my exhaust through the CAT. I have not had cats on it for about 6 months now and it is just now acting like that. They said it is not closing the loop (what ever that means). Has anyone else ever heard of that before. Please post and let me know your suggestions.
Thanks

 

If you removed your cats and didn't use some o2 sims or have some kind of tuning you will be having some kind of problem.

I just can't beleive you took you car to the dealership without cats on it. The dealerships around me would refuse the car and more then likely report it to the authorities.

Anyways, I doubt *just* not running through cats is the problem. Like I already said, get someone you know with autotap or some scan program and get your car scanned. Do it at the dealer if you want a fat bill.

 

man i take my car to the dealership with longtubes no cats and cam.lol i just make sure to close the cutout when i go in. but man even without sims your car will still run fine that will just cause an ses light. i think they are bull****ting you.
