Hi guys,
New to the forum...actually just joined a second ago. From Halifax NS. Have a 2010 Mazdaspeed 3. Cp-e CAI only modification for about 2 years now. A little over a month ago, started getting CEL. About 2 years ago (right after the CAI was installed, and car serviced for the first time) dealer had adjusted idle speed), I noticed it was difficult to get the car started when warm and sitting for a little while. This has been going on since then. No changes in performance or drive-ability. Car pulls normal, no back-fire, no nothing. I never had the car re-tuned after the CAI installation, but I didn't think there was any need to do that.
Anyways, since the CEL showed up, I've cleaned the MAF sensor, and cleared the code, but it kept coming back. Took it to the dealer for regular oil-change a few days ago, and asked them to investigate. They advised code was P0172 - System Too Rich. They also advised they ran some tests, and apparently the fuel pressure on the injectors is dropping significantly as the engine idles (and apparently, is supposed to be rising). They advised injectors are leaking, and need replacement. They did not specify which ones, but want to replace all 4. It will cost me $2,500 (with parts being 70% of the total). They also advised that the smell of gasoline can be noticed at the exhausts, which I can confirm. However, I seem to recall this was always the case ever since I got the car.
Now, I can get the injectors at a third their quoted price elsewhere (USA), and I can replace them myself if need be, but I thought I'd check if anybody else might have had any issued with their injectors on the MPS 3?
My speed has 48,000 km. I put maybe 5-6k km on it/year. It is parked underground from Nov 1 to May 1 each year, and I avoid driving it in the rain (unless I'm caught in it).
Warranty has expired for this particular issue (80,000 km or 3 years), but it seems to be way too early for something like this to go wrong?
Anybody had any similar issues?
I am also wondering if the CP-e CAI might have something to do with it? I am almost to the point of putting the stock intake in there just to see if it changes anything.
I would appreciate any of your feedback.
Thanks and regards,
