Okay, here it is:

2006 Mazda 6
V6 automatic
Completely stock

The CEL came on about 6 months ago and was the P2177 code. I did some research and came up with the purge solenoid valve. Called the dealer, they confirmed and said that was definitely the issue so I got the part and replaced it. Less than a week later the CEL came back on again. This time when we pulled the codes it came up with all the codes listed above.

The car drives perfect, the only issue that has come up at all was one time the car almost stalled at a light but then returned to normal idle and hasn't had an issue since.

P2177, P2179, P2187, P2189, P0131, P0151

I've looked for vacuum leaks and haven't found any yet but if you know of any specific trouble areas please let me know.

I'm also aware that all of these codes are related to the O2 sensors which I have ordered but really don't believe are the cause of the problems. Any help would be appreciated, thanks

 

It was not the o2 sensors as I suspected. I found the air intake tube from the airbox was torn on the underside in between the rivets. I was going to do a temp fix with some duct tape but didn't have any. Instead I wrapped it with butyl tape and sealed it all with electrical tape. If I'm right it will end up being permanent but if not I'm sure that I could get the tube from the dealer for under $40. As for now I've cleared the codes and all is clear for about 30 miles. I'll be taking it up to NJ

 

I am experiencing the same problem. I don't see any further posts. Should I assume your fix worked?
