Hi All,

Having a bit of bother with one of my cars.

Its a Fiesta RS Turbo EFI engine in an escort and running OFAB on a T3

It is having some problems which are beginning to drive me mad, Would appreciate any help i can get with them

- Idles Poorly, sounds really lumpy, Cleaned the ISCV and it got a bit bitter but still lumpy

- When on boost it picks up fine but as soon as you got flat out in any gear the car starts kangarooing, (lunges back and forward but boost pressure doesnt appear to change on the gauge) but is really violent till you let your foot off the gas

Car isn't chipped , Any ideas?
