woke up to a rough idle

Hey guys,

I need some help, I woke up this morning and started the car and was idling rough as can be, checked for the loose hose, and any other vacuum leaks, cleaned the maf. My af gauge was freaking out, wondering if it bad gas, or my fuel pump going bad.

Car has 109000miles on it, tomorrow morning ill be checking the plugs and anything else I come up with

Is your af going lean at idle only? definitely check for boost or exhaust leaks.

Update, af relaxed that was probably bad gas from turkey hill, I knew I had to replace the exhaust manifold gasket because it was leaking, checked the plugs and they are gapped correctly at just under .25, I've replaced my Pcv valve that was blocked. Car pulls awesome again now that the leak is fixed but the idlr is still off, like its laughing at me. Ha.....ha.....ha

I did remove my boost gauge to send back to autometer to be repaired. So that line is open in the car.
