P0174 existent after changing o2 sensor and brake booster line
I've had a p0174 for about 2 weeks now, I changed the brake booster vacuum line. Then yesterday I replaced the upstream bank 2 o2 sensor. Today the light came back with the same code also intermittent "cruise not avalible".
I have all new gaskets everywhere for my intake, new injectors, new fuel pressure regulator, new fuel filter, new plugs and coils, and no vacuum leaks from what I have seen(I'm going to double check). The only 2 things I can think of after looking around online is my maf sensor and the fact that longer then a month ago I was told my throttle body isn't closing all the way. However I'm inclined to dismiss the TB theory because I probably would have gotten a CEL up until recently.
So my question is where do I go from here? I'm leaning towards the maf sensor because it's affordable, however wouldn't I have a code for the other bank being lean? Since I only have the code for bank 2. My car runs perfectly fine, starts right up every morning. It seems like it hiccups sometimes when I enter onto the highway but that might be the car shifting and cutting me off in a way. Additionally is it ok for me to use the car like this? I need the car for school 5 days a week.

Once again (can be found in SEARCH) =
Easiest way to check for vacuum leaks in the engine bay is start with a cold engine (will be apparent why). Start car and immediately spray the probable/possible vacuum leak areas with some starter fluid (hence cold engine). If there is a leak you will hear the engine change r.p.m.'s.

So although mine is the "other one", might be worth a try.

@Alpha, you'd think so wouldn't you, but mine never did (other than when I forgot to plug it back in after cleaning it). Mine was as described in the thread. Been a while now and not once has it thrown the code again. I admit it's a bit strange.
Now if I could find the P0442 = Very small evap leak........another p.i.t.a.
