I am working on my streetka at the moment and have changed several sensors etc. I still have an issue which I think is fuel related.  Can anyone help with advice on the following issue.  When I start the car its fine on tick over, but when you try to accelerate sometimes it wont pick up the revs.  When it does go its fine in higher gear , but when you slow down to turn a corner or junctions the revs die and you have to wait for the revs to pick up again to carry on.  Does anybody think this is fuel pump issue as that is something I havent changed yet but do have one to put on if neccesary. The vehicle was stood up for three years, but is on the whole pretty good.  Waiting with hope .  Many thanks

Obviously you've changed plugs, leads and coil pack?

Is the engine earth good?

If it hasn't run for three years have you put fresh fuel in?

Hi yes changed plugs lambdas air and fuel sensors. Two new fuel filters and plenty of fuel. Checked as many plugs as have found but have recently found another which I don’t know what it is. Fuses are all good.  I do have a drain somewhere and am looking into that.  Thanks for any help.
