hello new here name is matt. i bought a 2011 cruze eco. the previous owner had a coolant leak and overheated it. i did a valve job new rings and bearing and surfaced the head. now the car runs great! but i am getting some codes and it will go into "limp mode" clear the codes and it will run fine again. the codes i am getting are P2227 P0236. i am wanting to test the boost sensor and the air intake temp sensor but do not know which wires to probe or what contacts to touch with volt meter to get a ohm reading. i really like this car and hope i can figure this out. any help is greatly appreciated!
