LIke the question says, how often does that happen? The CEL came on and has it scanned at autozone and it can up with a bad cat. FYI I have a magnaflow cat and it has been installed for about 8 months.
In 8 months if it wen't bad something made it go bad.
Semper Fi SAINT. May you rest in peace.
Running too rich, burning oil, if it went that fast something had to kill it. Did the car run rough or smoke or anything?
Semper Fi SAINT. May you rest in peace.
Not that I know of, what can I check for? Or where do I start to diagnose the prob?
Why do they think its the cat?
Semper Fi SAINT. May you rest in peace.
Well I had the CEL code scanned, and thats what it came back with. I had the car checked for exhaust leaks and there was nothing.
I didn't know the car could tell when its cat went bad. ????? Are they sure it wasn't just the O2 sensor ?
Semper Fi SAINT. May you rest in peace.
the after cat o2 sensor is what tells the computer how its working , when the after cat o2 fluctuates its voltage in similar pattern to the primary o2 , the computer sets a code for improper cat efficiency
or meaning the cat is back
depending on the cat you have , its very common for it to set a code
if you have gone 8 months with out a similar code , id just clear the code
it prob set due to being to cold out when it ran the test for the cat
how ever if it becomes a constant problem with the code , and there is no rattling or loss of power , doing 1 of the after cat o2 sensor mods will help it from coming back
either a simulator , or the spark plug anti fouler mod that places the sensor farther out of the exhaust stream
spark plug anti fouler mod? What is this? Is there instructions?

If only the link in that thread worked.

or you could not have been lazy ald looked on page 3 of that thread and found the instructions...
OR
you can look in
THIS THREAD (which is on the 2nd page of THIS VERY FORUM) amd see where I posted the same instructions on Friday!
eriC - What was the EXACT CODE you got when it was scanned? I got the magnaflow 94025 cat on my car and about every 2 months it would start throwing "poor catlytic efficency" codes. As 97 cavy said. if this was the first time in 8 months you got that code, just have it cleared, and not worry about it.
if it comes back, do the alti fouler mod
