Hey everyone, I have an update on my issue!
Car is back from dealer. I talked with tech that worked on it and he reprogrammed the ecm. The service manager said he has never replaced an ecm in
that particular vehicle. The tech told me that he has seen alot of wiring problems in a certain spot under the vehicle where the harness wraps around the oil pan.
needless to say the engine light came back on, same code, so we all agreed to replace the engine harness cause it is britle and stiff. and if that dont solve the ‘
problem they said bring it back and would put ecm in. They did not mention anything about correct oil type being an issue. So its back to the drawing board.
Harness will be in in about a week so i will update then with what ever happens.
