Will replace the map sensor to try that and will do a smoke test to see if any Splits in any of the hoses

Hi yes it's a auto not putting up any codes more then egr I deleted the egr first to see if they was the problem however One taking the pipes of the egr I seen someone tried To delete them with a old but of alloy that was not even fitting right So I got a kit and done it correctly and removed...

No not programmed out nor a engine light as this model range Rover sport (l320 2005) did not put up a engine light When the egr valve is deleted

I have a range rover sport l320 2005 drives really well until you stop at a junction or on a hill Then it is really slow to pull away no power till you build it up I have deleted the egr new air filter cant see any splits from turbo pipes Any Ideas what it could be Would a mag sensor do this
