So, the short version to the story is the cat(s) destroyed your engine. After the rebuild, you discovered & isolated the cause here. Is it plausible at all for a failure to keep the engine tuned (good spark plugs) and the associated misfires…to be a contributing factor to the cat’s degradation and eventual failure? *In the majority of cases, by the time the problem gets this bad-have the misfires, back-pressure and debris already ruined the bottom end of the engine?

I just sent a comment-question about which cat it could be that I have clogged. I had one more question, I don't have any error codes like p-420 etc that state I have a cat issue, but had a service shop look at it and say they thought it was the cats? Wouldn't I have an error code stating issue w the cats?

As the rest I'm going thru this w my 2006 Ser. How many cats did your daughters car have? I have 3 on mine its the 3.5l v6 so I'm trying to figure out how if possible to diagnose which one it could be before ultimately cutting them all out?

Would this also cause a car with a v6 to sound deeper like a v8 ?

does CEL come on with timing chain? and also what if it struggles to get to 3 on the rpm on park? does the gas pedal have to be floored? i notice i lost power driving back across a mountain.

My altima 2002 2.5l won't go passed 2k rpm. Replaced the following Maf sensor Throttle body Camshaft sensor Crankshaft sensor Spark plugs Coils Replaced old rotted air intake hose with a racing cold air intake And still doesn't go passed the 2k rpm Mark just revs up doesn't do anything passed that. I'm guessing the cat is clogged but idk man.

First don't guess. At the shop I previously owned I had a sigh "WE TEST NOT GUESS" it would have been cheaper to test it and put a cat in than to throw parts at it. Get a vacuum gauge there under $20 amzn.to/3vOBIxa connect it up and test like in the video. Rev the engine and hold a high rpm if the gauge initially gives a high reading and then starts to drop the cat is clogged. Here is a link to the front cat amzn.to/3r88aqG.

Well first What code? There is no direct code for a clogged cat. there is an efficiency below threshold code but that wont tell if the cat is clogged. You need to troubleshoot and not guess. A bad mass air flow sensor will do that as well. You could try a new MAFS or better yet a used one from the junk yard because new ones are not cheep. And or buy a vacuum gauge and test like i did in the video. If it fails the vacume test and you are in a non emission testing state. gut it like i did. if your state tests. Buy a new Cat.

My car does this after I drive 60 mph for a long person of time maybe 20 minutes but after sitting for 5 minutes at the most it’s back to normal I’m replacing my converter and o2 sensors soon to see if that’s why
