R34gt-t Intermittently Not Boosting

[FULOCK]

Hi all,

My R34 seems to have a mind of it own with how much boost it runs.

the car is stock besides cat back exhaust and pod filter.

when its going good, the boost gauge will go up about half way between the last and second last line on the stock gauge. The next time i put my foot down, it will only boost up to the first line after 0 on the gauge....???? and you can really feel the lack of power!!

i know these cars have that 2 stage boost thingy...... could the second stage not be kickin in and not getting the full 7psi or whatever stock is...????

and this is completely random.... after 30mins of goin like crap..... it will start boosting again....

anyone else had this..???

any help will be appreciated.

Never had that problem.

Two stage boost thingy?

How long have you had the car?

Have you had it for awhile & only just noticed the problem now, or has it been like that since you owned it?

One of my mate's s14 was running crap similar to what you described. We cleaned his afm & the problem has gone away since then. Possible solution?

Sorry can't be of any more help, try taking it to a competent mechanic if the problem gets any worse.

I'v been told that they have this by a few people....

have had the car only bout 4-5 month..... when ever it didnt go quite the best i just thought it was just having a moment or something.... but lately i noticed im actually not getting as much boost when its not goin good??

Question: by the factory gauge and stock boost... where should the needle go to?? first line after the 0, or a bit more??

I'll try cleaning the afm - see how that goes...

I'v noticed, once i start it and drive, the first few times i punch it when its warmed up - it hammers....

then, if i put my foot down again only a few mins later.... it hits less boost and dont go as good....????

it's really SHoIIITING ME!!!!
