Hey guys,
Car was running great just crossed 2k miles on the engine. Parked an hour later fired it up and noticed it sounded different. Sure enough when you step on it it just bogs down. I’m struggling to make 70mph in 4th gear holding WOT.
Codes attached. First thing I did was put in 8 gallons of fresh 93 and then I changed the 4 spark plugs with GM oem plugs. Turbo is making boost and if you WOT on the highway it will do some surging and sound normal for a second or 2 before bogging down hard in 3rd and 4th.
Anyone have an idea?
Thanks,

PS don’t mind the code for high/low voltage on coil pack it’s done that since day one.
