Good afternoon and thank you very much for your question.
Pleases can you tell me if your Freelander has manual or automatic transmission?
Took the freelander to Gap automotive and asked them to check the converter and the oxygen sensors, and told them what it was doing.
They called me and told me they had checked the car out and changed the plugs, and the vaccumm hose. They also cleaned the air intake mechanism.
The car runs like a charm.
Thank you so much for the help.
