Oh that's good. So i will pass even I gutted my precats ??? Because other members said to warm up the car then go do the test but the dealer will take your keys and finish others job then do the test so it'll be cold again ^.^
I have one pre-cat gutted on my car, and one that is definitely plugged. Car almost aced the driveclean I had done today. I have no doubts my car would have passed even with both cats gutted. However, I maintain my car all the time, at more than regular intervals, which I know is helping.
