Losing Power On Boost

[johnsy]

hey,

i need help to find the problem with my 93 r33 gtst.

everytime i step on the throttle it makes a fluffing type

noise like its maybe over fueling.

its hard to explain but only does it at top revs(around 5 to 7k)

and under load.

iv been told that it maybe be one of the coil packs but any other

suggestion would be great.

cheers,

Matt

fluffling noise?... does it missfire at all? when last did you change your plugs? how much power do you have? standard clutch? (sliping)

if you can answer those questions it will help us to diagnose the problem a little better.

cheers

i had this EXACT same problem. it aint ya coil packs.

Its def the sparkys. You can fix this problem for around forty dollars.

Go and buy 6x NGK BCPR6ES plugs.

From memory, Make sure they are gapped at 0.7mm.

Install.

Take your 33 for a blast.

Come back here and tell me if it works.

well said....but do not relly on these plugs for a long time....my NGK coppers only lasted for around 6 mnths not even that....irridiums are the best and from memory the gapping in 0.8-1mm....my mate had this problem on his 33 and as far as i have read along its definately the spark plugs....

^ always use 98..

Regap to them 0.8.. no need to go lower than that.. maybe 0.75 at max!!

Serviced your car recently?

[Krishy]

+1 to that....keep the gapping to 0.8 around that mark and do not use anything less then 98 even though the motor can run on a 95 fuel only if its completely stock....btw if you get your car fixed please let me knw what you had to replace to get the power back....i am having similar issues.....
