Finally fixed

[mcb]

I just want to share my esperience on this. It may help lots of fellow owners.

For some time now my MS3 started to trow code on irregular basis. I had p2177 p2187

At first i tought of a leak in my bov installation(its been installed june 2007) so looking around inspecting all my hoses and connection i found a loose nipple on my bpv. Fixed that cleared the code and Voila! no code for about a week.

Then i had the 2 code back again + p2097 and the LTFT was very odd(25) Still suspecting a leak somewhere before the turbo since it hold down pressure very well. I had change my CAI filter just the week before the code popped up. I finally disassembled my CAI the intercooler and the bpv to inspect the spark plugs. All of them where fine and gapped to spec exept one that was at .032. so i regapped all plugs to .030. While adjusting the back hose to the intercooler i put my hand on the tip(stock). Surprise it was very loose. So finally tighten the tip and cleared the code. Its not coding anymore. I still need to make a leak test to make sure everything after turbo is tight.

Even with a mostly stock (intake, bpv, rmm insert) car and even without any mechanics messing with it the tip came loose.

Lesson is: inspect all hoses connection once in a while.

I think Mazda was lazy with tightening the TIP. Mine was pretty loose when I installed the PG TIP. Glad you were able to find the mystery

Loose TIPs unfortunately seem to be a pretty common thing with these cars. I had meant to give mine a few extra inch lbs but hence I still can't get the energy to rip stuff apart to do it. And I haven't had a code signifying leak yet, so....yeah

My CPE TIP was also loose on compressor inlet. No codes, but after tightening it down car felt much smoother and not so lean as previously. So yeah, check your TIP.

Just all remember that a turbo inlet leak is raw unflitered air. Like running with no air filter. That will seriously shorten the life of the engine if allowed to continue. I don't know how much of a leak it takes to throw a code, but any unfiltered air is bad news. If you mod this car and have any half-assed ability to use simple hand tools, it pays to check the clamps regularly, given the frequency in which we are finding them coming loose.
