I have an 03, 5.3L AWD GMC Van. Changed the B5914 spark and B1901 TQ tables in the Tune and have been using this since Jan. Re-flashed what I thought was the stock tune back to the van. Brought it in for NYS inspection and OS update before warranty runs out.
The Emission failed, OBD readiness status for the Catalyst and Evaporative system : Not Ready.
If for :bash: I flashed the modified tune and not the stock tune would this cause that type of problem?
There were now MIL prior to and after the tune re-flash. There was about 7 mile trip to the dealer for the inspection. I thought the re-flash clears all code.
The new OS is in the van, the dealer wants me to put 100 miles on her and bring her back.
If I scan the ECM prior to the re-inspection and there are no codes. It should pass the inspection.
This isn't normal :nixweiss: any thought what going on ??
