I've been having evaporative system issues for over a year now. Vehicle idles very roughly and sometimes dies when at a stop. Initially, I was getting P0456 code. I replaced the gas cap and purge control valve (part 53032800-AA). The issue appeared to subside for about a week, and then check engine light, driveability issues returned, and the P0456 code returned. I then had the dealership evaluate, and they replaced the evap harness from the front to the rear canister. Specifically, they replaced parts 5166499-AA (proportional purge solenoid harness), 52102801-AD (canister Purge harness), 52102995-AG (canister to NVLD hose), and 5174236-AA (emissions hose pkg). The issues subsided for about a month, and then code P0441 appeared. The driveability issues started again too. Mildly at first and now the idling is very rough again.
Where do I go from here?
have the same problem?
