so my 05 srt4 doesn’t want to pass 4000 rpm, it drives normal under boost but it’s just when I get into boost the cel turns on and pops up p2074 code and doesn’t let me pass 4000rpm. I have changed wires, plugs gapped at .32, map sensor, crank sensor,and cam sensor... when that happens I turn off the car and start it again and it goes away but cel stays on. Any help please

See the attached troubleshooting guide thats an interesting code.. I'm guessing its a bad harness somewhere. back probe tips are cheap, take the time to troubleshoot the wiring. if you cant read this, send me a message, and ill send them that way.
