Could my cat be clogged?
So I know I need a new trans and about 2 months ago (I think lol) I got 2 p0420 codes, but I figured its just Cus I have a diff DP causing the CEL to come on, why would it take this long to come on though? :p
I've had this magnaflow downpipe for about 9 months now I believe. Could the cat be going bad already?? :confused: the car started running really rough about a week ago, surging and no power at all when I get down on the gas. Once it hits 2nd gear it bogs down and has no acceleration whatsoever. I was thinking it's my trans but could it also be my cat? |
Hi `Frank,
If your `cat or kitty is clogged, I'd tried giving the cat a laxative to see `if it helps ? :eek::confused: :rotfl: Sorry, I couldn't resist...:) ========================================== Do you smell a rotten `egg smell ?

I'm going to take it to a shop and maybe they can do a pressure test on it or something :p |

It could very well be the cat. These high-flows aren't made of the greatest quality, if your tune is running you rich you could destroy these things quick.
(think of the price difference between a real cat and these high-flows, that should tell you a lot) |

Edit: As a comparison I put the Magnaflow DP on my Monte a month or two before you did and I'm not experiencing any problems with mine clogging up yet. |
here in michigan we know longer have emissions testing....
I see your from florida...so why not just totally delete it? (cat) That should resolve the problem! |

My thinking is along the same lines. If the cat is clogged in 9 months time then putting another one on is just a 'band-aid'. You need to find the cause of the problem and solve it or you'll be back in the same position in short order. ;)

You get tuning software hooked up to it and monitor your LTFT :)
Or you clean all of your filters and sensors (esp MAF and o2) |
