S40 2.0D no dpf 2005 D4204T. new egr, throttle body cleaned. No warning lights illuminated. starts ok but with a definitive thump like an explosive detonation, mpg showing appx 50 mpg and sluggish acceleration when putting foot down, in 3rd-to 5 th gears with black/unburnt smoke being emitted(fairly big clouds of it as well) with the very occasional jerk/hesitation haven't got an obd2 reader but will get one once I work out the best/cheapest to get. very grateful for any suggestions, my thought process so far is 1) vacuum hoses 2) map sensor 3) maf sensor 4) injectors 5) turbo ? best regards David
