Too many codes!

[lunarF0XX]

My 2012 buick regal is stuck in limo mode I think. I've done just about everything I can think of it get it out. It's running so many codes, its not funny. The shop told me a cracked manifold so I replaced both intake and exhaust manifold. Also replaced the maf sensor. Air filters' cabin and intake. Both 02 sensors. Still reading all these codes and won't accelerate going down the road. I'm not a mechanic but I also can't afford another mechanic and I'm sick of putting money into this car if its not salvageable.

Clear all the codes and see what comes back. Your maf may still be the accelerating problem.

I cleared the codes and when it read it again, it usually pops up more codes. I'm gonna clean the throttle body next. Someone told me to change the sensor off of it but I can't seem to get it off.

I replaced both O2 sensors. Is the HO2 sensor a different one?

I had to get the throttle body changed when mine went into limp mode

Did you read the link? It lists other causes related to the O2 sensor plus did you buy a brand name sensor?

Yes I read the link and will check wiring when I get the chance. I also have my freeze frame data. Idk if it would help me get an answer

Have a qualified diagnostic tech analyze the issues. Probably cheaper than firing the parts canon repeatedly!
May not even be a sensor issue but as simple as a bad ground or power problem to sensors.
