dealer here in Alaska replaced head gaskets and head bolts under warranty, now truck is chugging under light and heavy acceleration. Dealer said no codes, they have changed the EGR valve, 2 and 7 inj harness, #8 injector, repaired #8 inj lead, replaced fuel pump o-rings and still has same problem. What should i suggest next? they have had my truck now for 8 WEEKS! :help
thanks, JJD2
