Will my range rover sport regain its power after I blank the egr vavles

blanking off the valves usually helps if the EGR valves are stuck and you will lose a little bit of fuel economy but blanlking compared to a functioning valve

but as you say its a cheap option

What r the purpose of the vavles because I live in guernsey where the speed limit is 35mph so I don't get much chance to floor it also will the black smoke go?
Hello Colin

the valves pipe a little bit of exhaust gas back into the engine which helps clean up the emissions

but when they go wrong the engine will feel very strangled

by all means try blanking the valves off 1st and see how you get on
