Okay, so in the very short amount of time I have owned my 330Ci, things have gone down hill real quick.
I have led myself to believe that my CCV valve needs replacing. I have some codes, but I'm not entirely sure what they may all be in reference too:
I keep losing oil (1 quart every couple hundred miles or so) and it would start misfiring when it idled too long.
Now there are a whole lot of new issues that I don't even know where to start from. The pictures of the codes are recent, as I scanned it because it's been acting up worse. Now, if I try to drive it, and try to accelerate normally at any point, the car starts to bog. I've checked all the vacuum lines I could get to and checked the air box to the TB for leaks/tears/splits. I couldn't find anything, (but the oil all over my engine by the CCV valve is what is making me change it and all the hoses).
I tried to drive the car down the street again today and it did it again, and then the EML light came on again. The last time this happened I was able to shut the car off and restart it and it would go away. Well, that worked for about 15 seconds, all three times I tried it. Definitely a new issue... I don't even know where to start on that!
Lastly, there is a ticking from the motor. The low oil pressure caused from the CCV leaks make me think that's the culprit. When I tear into the CCV valve this weekend, I want to take off the timing covers and inspect in there, too. Does anyone have any advice as to what I should specifically look for that could cause a ticking/tapping?
When I was messing with the scanner I was able to actuate a few tests: I did an injector test on each injector individually while it was running. It would cut out whichever injector I chose for 5 seconds, and all six made the car run worse. The car feels like it is misfiring, but no cylinder seems to be misfiring. When you rev the car up, it's very choppy, and sounds like a bad misfire. When you drive like this, the car chugs and bucks very badly. The car lately has either been bogging, and not misfiring, or misfiring/chugging when trying to drive. I did an "idle stabilization test" and it raised the RPMs up to 1500 for about 30 seconds. After that, the idle settled at about ~800 RPMs and it ran fine the whole 6 miles home.
I'm at a loss for what my issue, or issues could be. I feel like a fuel pressure regulator, fuel pump, the CCV valve, or an IAC could be the issue...
Or, any advice at all at this point? I'm starting to lose it. Every time I think I find the answer to an issue it gets worse, or another issue starts. I can't tell yet. Help please!
