Misfire codes take a while to set, so don't put a lot of value in their absence. Likewise, fuel condition fault programming is complex

Is your exhaust all in good shape - no holes?

I took the oil cap off the other day when the engine was warm and notice a little bit of white smoke coming out. Could this be a bad pcv valve causing this and therefore causing it run rich?

A bit of smoke is ok, it wasnt chuffing like a locomotive, was it?

No it was not chuffing, just a tiny bit of white smoke. Almost like when you were to light a match or something... not a lot.

Can anyone make sense of this freeze frame data to help me pinpoint the problem?

Did you ever figure out what was going on? I'm having the same exact problem with my 2004 XC70, p2188, worse after parking with car facing downhill. I replaced the MAF, and it went away for about 2 weeks then came back. And if I disconnect the battery the problem goes away for a couple hours then starts up again.

No, I have not figured it out. I replaced all the leaky vacuum hoses, it idles smoother and less rough. But I still get the running rich code, and then car surges on start up a few times until it levels out. If I clear the code, the car will start fine until the code sets, and then it will have issues upon starting. I can't figure it out.

I am getting P2188 and P2178, and a pending p0442 code sometimes.

Were you able to find the cause of this?
