Smoking the system is uses a Nitrogen smoke machine hooked up to the EVAP system to find the leak. Clogging the pipe will not achieve the same results.
To start I would make sure the code is the same and if so then have the system smoke tested.
I would buy the code reader the you can always get your emissions codes and post them here. AFter that we can discussdiagnostic and repair options.
