Good evening all.
My 2004 GTO has been running great until recently, when after starting it, it began to die after 5 secs or as if the PIM and ECM were not linked.
The mods are in my sig.
Replaced the ECM, followed the linking process, and with a 2004 oem file, it started and ran, like crap, as long as you gave it gas.
Proceed to flash the HPTuners file corresponding to my mods. Start it and it goes back the same issue-runs for 5 secs and dies!!
I tried several versions of the file-
1. Old HPT corresponding file, fail
2. New oem file with segments swapped, fail
3. New oem file with only Engine and Transmission segments swapped, fail
4. All versions with and without VATS, fail.
5. Apply an enhancement to oem file, success
6. Run oem file by itself, success
Finally, I flashed the oem with the 1 BAR MAF enhancement just to have a running vehicle. It does run like crap since none of the parameters match the modifications done the engine. And, I am not driving it.
This is the latest. Anyone has ever encountered this?
Next effort will be to just change maybe VE and fueling, the minimal, to new oem file to see if it makes a difference.
Thanks!
