If the MAF's were actually oily looking, a MAF cleaner will usually not be a good fix. You might want to replace them. How many miles on primary O2 sensors? Those are cheap and easy to change and do affect how the engine will run.
P0175 I think is a lean code. MAF's, primary O2's, and vacuum leaks can cause the code (among other reasons). Are you certain the vac line to the mufflers is connected or plugged off?[/QUOTE]
I have investigated and found a leak coming from the fuel tank ventilation which is located underneath the rear right wheel arch. No other leaks from anywhere. MAF's have normal readings. Might also change the MAP sensor on the left bank's intake manifold. Will change that ventilation system today and see if that gives me any results, hopefully it does
