Get your car into a specialist dealer and have a star diagnostic check on it. This will tell you where the problem lies and they can clear any fault codes to narrow the problem down. it may require a new Lambda (o2)sensor, they pick up contaminants and work less efficiently. As it is an older model the diagnostic check cant tell you if the Lambda sensor is actually faulty but will poss flag up a lambda fault. the lambda checks your emissions and the ecu then adjusts the mix accordingly. If the sensor is contaminated then it must be replaced and cannot be cleaned it will cost you approx £95 including labour fitted for a non merc one.

Broken throttle return spring and/or manifold air leak.
