Ok the check engine light is on, and when im driving it needs extra revs to pull off and once it gets going between 2-4000 rpm it can be really hesitant to accelerating and the check engine light keeps flashing then it will go ok, if i drop down a gear into say second coming to a junction it will do the same and become hesitant to go, on dual carriageway as long as over about 4000rpm it seams to be fine, it sounds like when your running out of petrol so guessing its a fuelling problem any suggestions would be grateful as its confusing the hell out of me!!!
Cheers
