Idle, Boost And Fuel Problems

[bazz]

hi,

got a 93 r33 manual turbo, when its idling it hunts slightly, but sometimes it just holds at certian revs, eg it will stay at 2rpm then drop really slowly. its also crap on petrol! gets about 270-320 on a full tank chnging at 2,500rpms. its always been running rich but now worse. ive changed the o2 sensor early this year. also it feels like there is no boost. i can hear an "air leak?" but the turbo gauge shows boost :S. also around the exhasut heaps of carbon. car also cuts out when i rev it, uselss to rev past 3000. any help would be really appreciated. i live on the gold coast, so if u know a descetn cheap mech please let me know

cheers

do as much as u can first bro

check all plugs gap to .8

tighten all intercooler clamps up

check and wiggle that every connector is on properly

then whilst engine running spray degreaser or soap over all vacuum lines/hoses and see if idle changes or bubbles

if does see were does might have split/leaking vac lines

good luck bro
