I have a 2012 Lancer GT, and while I don’t have a code or need to replace the O2 sensor or cat, the heat shield cover that goes on/around the cat is loose – this is causing a rattling/squeaking while idle. I can move I’m the cover freely. I noticed this cat cover has a worm gear hose clamp – do you know if this was done to stop any rattling/vibration? I put a hose clamp on mine, but it just goes around the cat cover and doesn’t fasten it to anything to prevent the vibrations. Can you help?

Frank Benavidez aka KID says:

EBay sells catalytic converters for cheap and sensors as well most mechanics will double the price on the catalytic converter and sensors better to shop around on the internet

I searched everywhere to check how many oxygen sensors my car has but it just talks about different types of models of Mitsubishi cars

Hello, I have that code in a 2006 lancer es. Do I replace the manifold integrated catalytic or the second under the car or o2 sensors?

I've clean the catalytic with cataclean, all monitors is complete even the catalytic is ready but the code comes back on.

Thanks in advance

Andy Alfonso says:

I just had my slow down light warning on my 2008 lancer. Took it to a mechanic and he didn't found any issues. But the scanner marked catalytic converter error. I feel the car is lacking power and make a funny vacuum cleaner noise. Can I try a cleaner first?

S Power says:

So, how do you FIX the problem, i.e., how you do replace the catalytic converter? I appreciate that you pointed out it's location as well as the sensors. That part is helpful and maybe with that information I can go ahead and attempt it myself.
