Hi my car losers speed at times going up hills somtimes with very small inclines. In 5th the car will not respond and slowly the revs and speed slowly fall back. I change gear but the same happens. does anyone have any ideas??

if it drives fine when turbo is on boost its the e.g.r valve give a lot of trouble on the 2.4 engines in the marea,croma and alfa 156&166 the best way to check this is to block the e.g.r at the throttle body using a piece of tin or light gauge steel make a solid gasket and fit it

Many thanks will try. Doormat
