The rattling was coming from the heat shield on the exhaust and not the catalytic converter and he showed me under the car. He removed that and the rattling disappeared. He installed the new denso sensors and the readings came out fine. The car felt more responsive but he noticed the Catalytic converter was not up to par but was not awful and expected that for a car with over 80k miles but the o2 reading were back to normal.
He said come back if there are any problems. I was charged $60 to install my o2 sensors.
I drove for the rest of the day and the same P0420 code reappeared. Called him back up and said to bring the car back tomorrow so he can do a freeze frame and confirm if the converter is bad.
If the converter is bad, I am going to have to order a GM original catalytic converter from the dealership which will cost nearly double of what I paid for the all in one from walker after the core charge.
I sent back the walker catalytic converter today and hopefully should have my money back by Monday.
What do you guys think guys is the catalytic converter defiantly the culprit? I have new sensors installed and the code reappeared. What else can cause a P0420 code?
This really does suck.
NY and California suck big time. Both listed as the most unfree states in the union. High taxes and tons of regulations as well.
Once I get the money, I want to head over to Texas where there is much more freedom that NY and much better weather too.
