i talked to the service coordinator again and he actually told me the error code.... as i am approaching elderly status, i have forgotten the actual number!
But it was related to an emission system leak --no specifically the carbon canister---

SD-- nice work!

OK.... car's back.....error code 1435 ---emission system leak --- found and carbon canister replaced.
The subsequent problem "re-readying" the system was said to be a problem in the diagnostic tool they were using......"ok, if you say so"

car runs the same as before i took it in...that is to say .... fine

no charge--- paid for the rental too


anyway, im glad to have it back.....but really hoping this doesn't happen often.
