A Flat Spot In R33 Turbo

[soultz]

when im driving sometimes, no matter what gear im in, the turbo will spool but the engine wont go anywhere, then seconds later it will realise and continue like normal, i usually have to take my foot off the accelerator and put it back on for it to stop, so when im doing 50ks then go to 3rd, and acceletrate it wont go anywhere till i take my foot offf and put it back on.

any ideas?

Might be clutch slip. Do the revs rise but car doesnt accelerate?

[soultz]

could be that actually, is there a way to definately determine it? lol

Chuck it in 4th gear going up a hill.

Give it a gutt full and watch the revs

If they go shooting up but car goes no where it's the clutch

[soultz]

I was thinking it can't be that because it happens after I chuck it in gear and it happens if I just drive in the same gear and not change it...

[Manuel Kasko]

Clutch slip doesn't happen just after or during a gear change.

Mine is currently slipping and only happens in 3rd,4th and 5th gear once it gets to about 4000rpm

These words still make it sound like its clutch slip. Where is the friction point on the clutch? High up the top?

[soultz]

Yeah I'd say high up top

[Bsa]

Sounds like clutch is gone

[Excuses]

Had same issue in mine, 4000 in 4th an 5th it would slip. Best bet clutch, like everyone else has stated.

ive since discovered, **sometimes** when i put my foot on the clutch as im coming to a stop the car will act like its conking out (engine light comes on, hicas comes on, revs go to 0) then when i take my foot off, the lights go away and the engine goes back to how it was? is that a transmission problem?

[DVS JEZ]

Does that happen in neutral or only when in gear?

If only in gear then the clutch is buggered and its not disengaging correctly

Atmo BOV?

[soultz]

its a blitz atmo bov yes

its when i put the clutch in, so disengaging it

[89CAL]

Thats why its stalling, not clutch related...

Your atmo BOV is causing your car to overfuel when its returning to idle and making it stall

Need some more info. If u keep it in gear with the clutch in does it try and stall or only when u are slowing?

89cal may be right about the bov but need more info

[soultz]

when im driving, say 50klms and i put the clutch in, sometimes it will stall and then kick in again

[Bsa]

Remove the bov see if it still does it

[soultz]

i havnt got anything to replace it with though...what if i tighten the spring more? its really loose at the moment...

Cut the side out of a coke can and slide it between the bov and intake to block the hole. That will tell you if its the bov causing the issue.

I'm guessing it is the problem.
