there are no more engine codes, the dealer replaced the ecu, maf, t-map, map, some other sensors, o2 sensor, charge piping and intercooler. still has the same problem, thats why i'm curious is there is a lemon law or anything since its still under warranty and been down for 17 business days for the same problem. gm is sending an engineer too look it over
