First off i wanna go through what the last few months have been. first off was an oil leak from the valve cover gasket which was normal from looking stuff up we didnt replace it but a friend put sealant on the gasket and did stop the leak cause within 2 weeks from an oil change i was near empty. then maybe a week or two later i noticed big stuttering while trying to pass someone. it was misfiring random and a cylinder but we did replace all 4 spark plugs and ignition coil even though it was the coil as one of the things was bad. now we have codes for running lean at first it was the p2270 H20S sensor 2 bank 1 but my bluetooth reader doesnt show that sensor but the voltage looked fine. the fuel/air comm ratio is at 14.6/7. a friend tells me my fuel pressure is low as that sits about 43 psi idle. but i never got this code untill i looked at my maf sensor but that was clean but i did break the clip to hold it but ever since ive been thinking something happened. atm im getting p0171 system too lean. we can rule out the evap purge valve cause i replaced that cause of the load clicking it was doing. if you guys want pics just let me know as i do know im i can tell it is running lean as i think my mpg is lower

 

Luckily enough it was just the intake tube got all 3 clamps replaced just incase but now for the valve Cover Gasket but other than that no error codes
