I was on the drive to work this morning and after my usual pull up the entrance ramp a CEL was triggered. This is the second or third time this has come on since getting my Buschur turboback a few months back. I have a Cat, so I'm not sure that is the problem. I thought no CEL's were supposed to be triggered with this exhaust?

Think I should just reset the ECU again, or is this a more serious problem? Is it just in need of a tune? Any help would be appreciated.

 

Go to autozone and have the code pulled.

 

I have the same setup amongst other things. I've triggered the ol' "cat inefficiency" code a couple times too. My Dad has a diagnostic reader so he just clears it out. It seems as soon as it's cleared it just pops back in to the "pending" area right away. It doesnt really bother me to be honest.

 

Just go ahead and get a 02 sim..... $50bucks no worries.

 

Does any high-flow cat not set a 0420? First make sure that's what you're getting. If so do the anti-fouler thing. I have the same exhaust and the fix takes care of it. I just used one long anti-fouler rather than two shorts.

It was a P0420. Is there a specific kind of "long" anti-fouler, or are they all the same threading and diameter?

 

You want the 18mm long. Autozone, Advance, Pep Boys, etc. all have them.

If you are running catless...your ECU is reading too much exhaust gas going thru so all you need to do is to get a mechanical o2 cell fix.

just take the cat out. Cats are for boys. step into the Man's world... where pollution runs free and oils drip without care! where your lungs are black as your exhaust.

lol

it could be that your cat is burnt up. or loose inside. this happens time to time.

 

better yet , for 5bucks = https://www.evolutionm.net/forums/sh...d.php?t=114931

 

Thanks guys. Did this last night and cleared the P0420 code. Hopefully I don't see this pop up again.

 

I just got a p0420 code and mitsu said it was because of an aftermarket exhaust( I have a vishnu exhaust). I would advise anyone NOT to go there for codes to be pulled or they will void your warranty relating to that if you have an aftermarket exhaust.

 

Or 30 bucks and take 5 minutes to install
