Leaking cac, plugged exhaust, leaking intake piping or even bad turbo. We replace intake sensor all the time. Riemember ECM only knows what its being told. If its getting bad data it will not preform well.

Ok doke thanks, it has recent turbo and ecm intake sensor changed multiple times( there are two side by each on this model). There was a thread somewhere about coolant leaking in actuator onto control board but I don’t think this is the case here. I will get after these other possible items
