Hi, so a few days ago, my 2009 MS3 threw a CEL upon startup. Pulled the code and it's the P2187, lean at idle.
Throughout the life of the CEL, the car was really normal. Of course I didn't really push it. But I did push it once, just to see if I was still getting boost (because everything else has been normal).
And yep, boost as usual. I don't have a boost gauge or a numerical way of measuring boost, but trust me, the car did its thing.
Fast forward a few days, and the CEL disappeared. What's going on?
My mods are:
- Mazdaspeed CAI w/air straightener
- CP-E Turbo Inlet
- Turbosmart BPV
- CP-E RMM
- All the shifting mods
Thanks!
