R33 Problems? Help Lol

[GuestyR33]

Hey peoples...

Ok so my mate is having a problem with his r33 gtst.

Symptoms are chugging / shuddering when accelerating

generally only happens once the car has been driving for a

little while.

I think its a vacuum leak... i had a quick look for loose hose

connection etc but found nothing... i'm guessing when the car

warms up it open a split in a hose connection etc?

has anyone had this problem?

any ideas?

suggestions to fix?

ok any help would be much appreciated...

regards

Simon

hey man i had a simallar problem with mine all it ended up being was one of them rubber elbow hoses on the intercooler piping and it only opened up when the car wa son boost just a thought hopefully it helps

my suggestion is look harder for that vac leak

i had the exact same problem, but when i opened the bonnet with the engine on all i could hear was PSSSSSSSSSSSSSSSS

shouldn't be too hard to find!

Ok... So i have checked every vacuum hose connection... intercooler pipes etc

i cant find a leak anywhere. there's no hissing sounds.. honestly appears as though

its not vacuum...? i checked all the coil packs. all of them seem to be working fine.

is it possible the air flow meter is playing up? i cant think of anything else...

It doesn't shudder when it hits boost... more on take off once the car is warm...

any suggestions would be appreciated...

cheers

Definitely sounds like a vacuum leak. A good way to check without a smoke machine that mechanics use it to make up a solution of soapy water, put it over cooler pipes and vacuum hoses and look for bubbles.

How did you check all the coil packs?

Did you swap them from another car?
