Hi i have had this problem for a few months now. we had a bit of bad weather and since then my car has been very sluggish when accelerating especially once ive driven it then got back in a few hours later and driven it again.

when im driving at a steady speed it will lose power and i have to put my foot fully down to gain speed again it will splutter and then gain speed once this happens once it is almost continual. also sometimes when i stop the revs jump from almost dieing to normal continuously but it never dies.

i have changed the spark plugs and the air flow meter but the problem persists.

any help would be appreciated.

kind regards sam.

Often the tank vent valve is the culprit.
