Is This My Catalytic Converter

Question: Is This My Catalytic Converter,
I have an 06 Nissan Murano SL. It’s a gorgeous car but has given many problems.. I know it eventually needs a new catalytic converter but I think now it needs one for sure soon. When I do a lot of stops I’ll press the gas and the car won’t go until a few seconds of pressing on the gas. Then it lurches forward. It used to do that only once in awhile now it does it almost every time. When I make stops the car makes a rumbling noise. I know I need new brake pads as well by just looking at them the pad is super worn down. I’m going to purchase the parts on my own for the cat and brake pads, how much do u think I’ll be charged in labor? And is it sounding like my cat needs to go soon?

Best answer for Is This My Catalytic Converter

One, your catalytic converter, unless thoroughly clogged, is not going to cause problems like that. They stink like rotten eggs when very new, or very bad.
Check your laws on the internet for your state, your state may not require catalytic converters on vehicles, and if they don’t, cut if off, put in a piece of straight pipe and sell the junk cat to the scrap yard, they’re worth up to $200 each due to precious metals in them.
The throttle response sounds like a dirty fuel injector system, or possibly dirty fuel delivery component, like a fuel filter, fuel pump or a bad line (clog, leaky vapor return line, etc.)
Since your brakes seem to be grinding, you can count on getting the rotors turned as well (most shops do this for 20-40 dollars per rotor) – When your brakes are grinding, the pad is gone & the metal shoe grinds in to the rotor metal, causing damage.
Most shops charge $100 per hour & up. I would suggest doing a “Sea Foam Treatment” (costs under $20, you can do it yourself & helps tons!) Google that, & if you have tools & are mechanically inclined, front brakes (odds are, what is bad) are easy to replace. Buy a Chilton’s manual (or other repair your own car type manual, almost all auto parts stores sell them for $20 or so) for your specific vehicle, make sure you have the necessary tools (listed in said repair manual), buy the parts, borrow a set of jack stands & a hydraulic jack & reserve a Saturday to do it yourself (or with friends, bring beer/pop/food).
If you don’t feel like learning to do brakes & a Sea Foam treatment, most shops will do your brakes & rotors for the cost of parts (they mark them up, way up) and a couple of hours labor. Then they will investigate your throttle issue & it could cost plenty, I strongly recommend a Sea Foam treatment (again, Google it) to sea if it fixes the throttle delay.
Don’t forget to choose a best answer when you figure his all out & I hope it works out well for you.
