I have a 2006 Mitsubishi Raider Duro Cross with the 4.7 and its throwing a check engine light saying 1 or more o2 sensors might be bad. Any tips on figuring out what needs to be replaced? Or do I just spend the 200 bucks on all 4 sensors?

 

Lets start with what code/s are present.

 

I didn't manage to get the printout from O'Reilly as to the number code but it was something about bank 1 and 2 I believe o2 sensors. Not sure if it has anything to do with the precats but it doesn't have a cat anymore.

 

If you have no cats, changing the sensors wont help. You need to do the non-fouler trick.

 

Well it looks like it still has the pre cats but I don't see a regular cat farther down the pipe just the 2 bulges right after the headers. What's the trick you speak of?

 

Is your exhaust factory? Factory exhaust comes from the manifolds to a cat, then a resonator, then a muffler then another resonator behind the rear wheels.

Google is your friend:

 

Wow Thats pretty cool and its an aftermarket exhaust

 

What kind? Headers to back? True duals? Inquiring minds want to know!! Plus we need pics of that bad boy.....

 

It's got a standard single out exhaust it seems to be just straight pipe from the little bulges after the headers on out and any suggestions on how to post pics on here from a phone? Lol

 

Can't from a phone. Open a free account at photobucket, upload photos there then copy the "IMG" link and paste it in your post here.
