Hi all. having a problem with acceleration at low revs - really apparent on mild road inclines when cold. Been running fine then went out one day recently and from cold would hardly accelerate up a mild incline. Foot to the floor and it started to gather momentum (not really accelerate) but improved as revs picked up. Have replaced the fuel filter (no change) and recently had a new air filter. Have done some research and a gummed-up EGR and inlet manifold seemed to fit the symptoms but it can apparently be checked if you disable the EGR by disconnecting and closing the flexible pipe connection at the EGR. This I did with no noticeable change to acceleration so it doesn't look like the EGR? (but why would the EGR suddenly cause my problem in any case - surely this would likely be a gradual loss of performance as crud built up?). Could it be the turbo or a sensor, do you think? Folk lore suggests that if it is the turbo there should be loads of black smoke - there isn't - and there are no dash warning lights. Also Once it gets up to speed it thunders along as previously. Any thoughts would be gratefully received.
