My citroen berlingo wont rev above 45000 revs and is worse when under load. I chnged the air filter and Spark plugs(that were perfect tan brown colour) but have had no effect. The power output varies sometime higher sometimes lower. I need the car fixed due to the colossal amount of fuel is using. Any ideas?

hi,
Have already cleaned the injectors and replaced fuel filter. I had fault code p0420 (catalyst below efficiency bank 1) Do you think this could be an issue with the cat or exhaust? Its causing the car to be drastically underpowered
Thanks
