R32 gtst revs funny*BIG HELP PLEASE*

[TRDsupra]

Hi all,

for the last 3-4 weeks I have noticed the funny revs everytime I put the gear to neutral.

it only happened when the turbo has kicked in.

It would go from 5 th gear at 2800rpm to (put in neutral) down to 300 and up to the normal 800-1000rpm.

I have changed the ACC but it did nothing....

Also my mate's R32 gtst auto always cutout when the engine is hot. Sometimes can't start for 10 minutes. bloody scary to drive when it decided to die in the middle of a busy intersection.

took both car to the mechanic and they have no idea what is wrong with the car.

maybe you guys know....

Please help....

Much appreciated.

P.S I need a service manual for the R32 gtst.

if anyone have a copy please pass one on to me....

is it only in 5th? or is it in any gear after being on boost?

do you have an atmo venting BOV by any chance?

[TRDsupra]

yeah i have a ssqv

also in evry gears after boost

you think it might be the bov????

How do I stop it????

Thanks in advance

What about me mate problem???? )

Your problem sounds like its caused by the blow off valve. I had the same problem and replaced the turbosmart atmo venting bov with the standard plumb-back and problem solved...

its caused by the already metered air being vented to the atmosphere, but the fuel still being fed in to go with that air, hence causing it to run really rich when you put it into neutral, so basically whats happening is your engine is overfuelling to the point where it bogs down, and sometimes will even stall, 'coz it floods with fuel.

My suggestion: Get a recirculating BOV.... better for the car, and doesn't make the wanky PSSSSSSSSSSSSSHT sound

Yeah, I had the exact same problem. My R31 coupe came over with no BOV and if I was on boost and just dipped the clutch the revs would drop right down and the warning lights would start flashing and sometimes stall.

I installed a bosch plumb back BOV and the problem was cured instantly.
