Hello, Need some help on a few problems with me RST. Basically it's very jerky on light throttle, shakes a bit like there is a blockage or something. No problems at all when on boost as pulls strongly. My fuel pump is making quite a loud noise as well. Just does not seem to like it when driving off boost for some strange reason!
Also got a oil leak from the right side of the block when looking from the front. Under the dizzy as can see a trickle when I look at it.
Car is lightly modified but not chipped.
Thanks for any help as car is driving me mad!

 

the oil leak under the dizzy's will possibly be the o ring one the dizzy's

as far as the other problem could be over fuellingthat low rev, how many boost are you running, if standard then it should be roughy 8psi lets start there

 

fuel pump - loud noise = fooked, get a new pump before it runs lean and blows up
