start by cearing codes and see what comes back, definitly have a egr valve sticking open, thats the p1335 code , the iat sensor is mounted in the intake , dont buy anything other than a egr valve , clear all those codes and restart diagnosis , then see what codeds come back, the p0488 code is possibly even a code that shouldnt be there , there was a reprogram to eliminate that code all together awhile back, truck may need the latest calibration

thank you for the quick respond, i did blocked the egr, will that has something to so with it, i but a freeze plug in the exhust side, i did erase the codes and the ones that came back are the the iat sensor and the p1335 egr, is the iat sensor togeter to the mass sensor????

just because the egr is blocked doesnt mean it still cant cause problems , that is a big misunderstanding ,boost pressure can still push it open on the boost/or intake side of it , the iat sesor can interfere with mass air flow readings , there is also a iat in with the mass air flow sensor mounted in the intake , they are not known to give much trouble but can
