How many people have had a cel thrown with a hiflow cat or no cat at all?

 

unless you do something about it, you're almost guaranteed to eventually get a code. In my 2.2 took over a year. In my 2.0 took about 3 days lol. But you'll get one eventually. Unless your secondary 02 sensor isn't working, in which case you'll get a code for the sensor.

 

it just lets you know that your check engine light still works, don't worry about it

 

yeah i have one from my high flow cat

 

my code says that the cat can't get up to temp. and it is inefficient, I have just a vibrant high flow cat.

 

You can permanently clear the code. It is not a big deal.
