First thing to check for code 54 is coolant level and sensor, holes in air duct between air cleaner an dthrottle plate and anyhoses/grommets with holes in them as well as full oil level. Make sure the iat is the correct one and being plastic shold n't matter just holes in duct owrk cause it can't work right. It might be a mpa sensor problem as well with ahole in vacuum line leading to it. And btw what engis is this?
