Default '03 Express 6.0L-codes PO101,PO171,PO174
6.0L, 125,000mi., gives MAF(Mass Air Flow) & "lean" codes. some missing particularly during warm up. also outside temps less than 30 degrees.
std,paper air filter-MAF sensor looks clean-

Anyone had problems with these codes with 6.0L engine ???

Thanks for your help !!
