hey guys,

My 05 z has berk test pipes, and about 1000 miles later, check light turn on.
I check the code, and it was P0420 which is caused by cat. converter.
What if z experiences other problems while the engine light is on?

I knew some of cars blinks the engine light when they have multiple problems.
Does Z also blink when it has more than one problem ?

thank you,.

 

shoulda bought an 03

 

When you checked it the other codes would have shown up.. don't worry it will turn on and off every 500-1000 miles you can check to make sure that's the only code being thrown .
