Gtr Cutting Out

[foney]

Hey, i have a 1990 R32 GTR.. And i have just a few problems that i was woundering if anyone mite have a clue what it might be.

Firstly My All wheel drive system.. The fuse is in the fuse box, and has been replaced. The light does not come on and im running or rear wheel drive all the time.. its not a major problem but just would like to have all wheel drive.

Secondly. some times while driving normaly and more so when giving it some it runs real ruff idles low etc. the way i fix this is to turn the key off and turn it back on again while still moving and it goes away? I have a power FC, split fire coil packs, ridum plugs, 3inch exhaust, pods,.. i have checked all wiring and earth points and even reset the computer and retuned it..

some one please help,

^^^ This forces rear wheel only mode.

Id take it to someone who knows GTRs, as there sounds like a problem with ATTESA (or ABS, as they share sensors).

If I had to put money/take a guess on the problem Id say your ATTESA pump is shagged.

ive pulled the fuse to the atessa and it still has that cutting out problem.. there are not to many people up here that know GTRs Maybe its my air flow meters.

Are maybe your rite about my etessa pump being shagged..

thats heaps for your help mate.

regards the running rough and bad idle.

check the usual suspects.

Spark plugs (buy a set of NGK copper plugs with heat range of 6 and a gap of 0.8mm) - $4 each

Check and clean your AFM's (may possibly need re-soldering - search this forum for AFM+SOLDER to find details)

AAC valve - clean it - instructions are available in the DIY section.

all of the above will simply take time and very little dollars compared to what you've already spent on re-tuning and so forth.
