Took my O1 cobra to the track a month ago for the first time. Mph was pretty low so I brought her home. A while back I installed a catch can system, I discovered it was clogged up pressurizing my crank case so all of my spark plug tunnels were full of oil.
This past weekend I replaced all my plugs, installed new pcv valves, I had a K&N filter on the end of my mass air meter but relocated it to inside my fender well, Yanked off my iac restrictor plate and swapped my slp lm1 catback for a Mac.
I took her for a drive yesterday and it seems to accelerate well but cruising at a steady speed it has a stumble to it. My check engine light came on. I ran to oreillys and pulled codes p1O7O and p1O74 banks 1 and 2 lean.
Came home with a can of mass air cleaner, cleaned it and checked for vacuum leaks, there are none.
Does anyone have a suggestion as to what should be checked next?
