got a problem. at idle all good give it part throttle and refs will continously fluctuate (up and down) with more than half or full thottle problems dissapears with a bit of a shudder cruising around at 50kms 2700 rpm roughly car will speed up and slow down with part throttle not bein increased or decreased again full thottle problems dissapear or if you give it a bit more thottle it will speed up and have no issues until you go to decelerate change gear and gas back on it shudders a little any ideas or remedies would cleaning the aac valve help

a friend of mine had a similar problem with his silvia, he had water in the valley and it was getting to the injectors.

cleaned and dried it and it was sweet, could also be coilpacks (maybe)

hey mate, had the same thing in my 33 gtst. did u change the coolant? mine would idle at 700, then go to 2k and back... got it to the mechanics, apparently i didnt bleed the it properly, trapped air and thermo couldnt tell what temp it was. so yea, that what happened to mine, possibly urs?

Cheers.

mine is also starting to do that ever since i got exhaust, fmic, blow off valve and upped the boost , theres forum bout it on here already, and from what iv read it seems to mostly be due coils or plugs
