DTC reading =P0031,0037,0032,0038,0035,0041??? Help!!
It started out when it felt like it ran out of gas, I put gas in it, started up and ran fine till it warmed up maybe 2 miles!! Figured fuel pump but no I just changed it 3 months ago, filter, changed it, o2 sensors changed them, still doing it (it being won’t get up over 2500 rpms, going up hill bogs down to about 20 mph!! Put pressure on it bogs down to the point of where it died on the hwy.) Funny Thing is if I turn off the engine even for a second in neutral coasting and restart it it runs fine for a couple minutes can hit 3500+rpms then no acceleration less feathering it!! Once rolling it can Cruze if I don’t give it to much gas!!
Now it’s got the other 2 codes and I’m lucky to get it to reset for 30 seconds.
I’m driving like this and it sucks!!
I took real time photos of the data stream I’ll include while it was f+*~^g up!!
Please help me!! It’s a good truck I don’t want to retire it!!!

From running good to fully fuc+<d
