1998 R34 GTT A/T sedan

[RyanN]

I just bought a 1998 R34 Skyline GT-T sedan less than a month ago and have started to have problems. From checking out the forum i see that the r34's have had quite a few problems to do with the electrical side of things. When i first played around with the car the 'TCS' would only turn off and not back on but after resetting the ECU it started to work fine, the switch actually started to turn it off and on; however i've had this other problem which seems to happen once in awhile - i would be cruising down the highway at 100 then suddenly the 'TCS off', 'slip' and 'check engine' lights would come on but nothing would change in the way the car was running. ie: the engine still sounds the same and doesn't loose power or anything. i checked the instruments when this happens and everything is ok, oil press is fine and eng temp fine. Once i arrive at work i turn the car off then back on and everythings back to normal, is it? (could it have something to do with the sensors?)

PS. ive checked the whole car out when i got it - oil, water levels and used hi-pressure air to remove alot of built up dust and junk that collected in the fusebox and wiring.

thanks in advance!

What wheels do you have on the car? If the rolling diameter of the front and rear are different it activates the traction control.

And when you've answered that question post a pic or two of your car

It has the stock 17" wheels.

Ive got a few pics of it over on cardomain:

im going to keep it looking stock for awhile since i would rather spend the money on performance. ive already bought a 300x600x75 intercooler and 450hp turbo. The build up begins......

Nice colour. The seats look different to mine and most that I've seen.

[666DAN]

Dunno the seats look like my ones...the type that easily stain and get brown water marks LOL..but I've found some stuff call Orange Power stain remover gets them back to new!!!

[RyanN]

yep, the front and backseats need a scrub. One thing about japanese cars is that the ashtrays are always really worn, same with my old supra - removed the centre console and there was ash all over the place.

back to the problem at hand, the 'check engine' light and TCS still turns off randomly, however it usually happens halfway into my comute (once the engines warmed up -sometimes). Happened this morning and this time it felt like the engine load had been taken off but the car still drove at the same speed, and of all things it felt more responsive when accelerating. What the hell is going on?

hey, can u tell me the colour code for that car ? is it athelete silver or sonic silver ?

yeh, code colour would be good.

[RyanN]

i believe its sonic silver, its a darker silver than most silvers almost in between gunmetal grey and silver. Which part on the plate tells you the code?

Over the weekend i did some engine checksand found a huge vacume leak in a hose going between the intake and this little black sensor thing tucked away next to the left suspension strut and brake cylinder, repaired it and now the boost gauge goes into vacume when idling, thats normal right? when i got it it never went below 0. I though it might of fixed this TCS problem but no, still have that problem. Also i tested the BOV which worked extremly well except for when the engine warmed up and idled below 1000rpm, causing it to struggle then stall. Driving was fine, the BOV goes off under hardly any boost making a loud pfffshhhhhhh noise which sounded really awesome even with just an A/T. Don't know how i could fix the stall problem since the GFB Mach 1 BOV spring can't be adjusted. any ideas?

umm it should say on the plate. its a 3digit figure. e.g TV1 etc

[RyanN]

i'll go out and check it at lunchtime, im currently at work

Whats the boost/vacume gauge meant to show at full stock boost? when i got the car i would show no vacume but would max out just below the halfway line from +1(which is about 5-6PSI, when i fixed the vacume leak it now averages about halfway in vacume then max boost at just past the halfway mark which i about 8-10 PSI.

I didn't realise R34s came in Sonic?? My R33 SII is Sonic Silver Metallic

[E_Lu-SHuN]

type in ur vin number and ill check your color code through fast software

[RyanN]

Vin: 6u90000er34011763

[E_Lu-SHuN]

color code is KR4

i have no idea how to translate the code....some sort of silver

[NJR 34GTT]

Boost at vaumn under idle is normal yes.

My suggestion for fixing the idle/stall, get rid of the atmo bov.

most turbo cars don't have have a problem with the atmo BOVs, so why does the r34?

[Silver'sR33]

Ok cool then, yeah mine is KR4 too according to FAST. What;s the difference between sonic and sparkling?

Millenium Jade and Silica Breath look awesome
