Hey everyone new to the site. I have a couple questions regarding my 2008 gmc acadia. I bought it about 6 months ago and the engine light keeps coming on for p1174.
I took it to a couple shops and they seem to fail to find a solution to my problem. It runs lean and drinks a insane amount of fuel. Checked for vacuum leaks on top of engine but didn't find any. But in my throttle body and intake tube I have what appears to be engine oil. Any advice on what to look for and replace would be appreciated. Also I replaces the maf sensor and cleaned the map. Thanks

My 2007 does the same thing with the oil. I did the breather fix and it helped a little, but still does it. 190,000 miles so far and it doesn't cause any issues, it'* just annoying knowing that it is happening.
I don't think the P1174 is related. For P1174 I'd look into:
1. Bad oxygen sensor(*)
2. Injector problem
3. Ignition problem
. . . in that order.
If the oil in the intake were causing this, it would be affecting both banks.
The 02 sensors are working fine. Would anyone know the short and long term fuel trims? And if the intake manifold is oily and a bit dirty, is there a easier way to clean without removing it? And i connected to fuel pressure gage and pulsed the injectors and didn't see anything out of the ordinary. Maybe I should take it to get injectors cleaned?
