Maybe your water leak is leaking on your alternator/electrics or engine management sensors.
Clean all the sencors up and check them. Another idea is when its idling push and pull slightly on the inlet manifold and see if that effects the idle as a buggered inlet manifold gasket can cause those rpm symptoms. Also Connect your s12 to another car with jump leads with the other car running and see if that helps as 12.5v is not enough output at the battery with the engine running.As you say it should be ok but i dont know how fussy your management is oh..and.........3000gt are big and heavy lol

 - I can't see past the manifold and turbo, but have felt with my hands, and can't feel a hose off or split (though it almost certainly is) - Damn, wish this had happened at Jae when my mechanics were handy!  I think you're right about the power - 12.5 volts when running's not enough is it? - I'll hook up the fiesta (or Tom's Range Rover if he nips up!) - Either way, it'll be nice it it idles smoothly (I think it's just that with the electrics, water leak AND erratic running problem all happening at once, I'm WELL p*ssed off! - If they'd happened separately, I'd have only had to take 'em one at a time  )Will also check the inlet mani as suggested, but seriously mate - Cheers for the info!  PS - Paul? - 3000GT's are BIG man - Lotta weight to pull, and they pretty much drive themselves! (Where's the fun in that eh? )PPS - yer sound too happy about both the missus AND the car going?!?! - ...have you had a bump on the head?! Ironic! - I was going to nip up and show you the beastie during the five minutes or so it was actually running well, but then she got poorly again...

funnily enough the doc has diagnosed me with acute depression!!! it affects me very strangely. All went wrong when i bought a replacement T3 and it was noo good. I started then. Anyway, Im pleased with the 3000gt. Reliable fairly fast (320bhp uk spec) and ok to drive. I will fix silvia fully before she goes to a new home i think.

12.5 is definatley to low a voltage. It should be ~13.5v. Do you have a multimeter? If so, leave the car off and disconnect the battery, switch the multimeter to the continuity tester (the one that beeps) and check the line between the alternator and the posotive clip for the battery. It should beep, or give a really low reading as its as close to a short circuit as your likley to get.
Failing that, measure the potential difference between the cars body and the output of the alternator. Also, not sure on a DET engine, but I would imagine it will have a second smaller wire which controlls the regulator, check that is firmly connected, or else it wont charge the battery. Sounds to me like your alternator is dead to be honest. Edit- Apparantly I should read the whole post before replying, sounds like youve got it all in hand.

The tip about the wire to the regulator sounds promising - I 'll check if I have one, and if so, if it's connected! Cheers guys, Den.

Den, I thought you were bringing the car up to me to have the wiring sorted?

Yep - I'm dying to bring her up mate - Unfortunately a bloody hose split/leaks (and it's near the tubby! ), and in addition to that, I don't think she'll make it to yours! - I got home (Just!) when I noticed the erratic idling problem - I've charged the battery up now, but it's still erratic mate?!?! - Also missing a bit, and can't risk driving it as a result... Might see if I can borrow a trailer.... Will DEF. be up though mate - it'll be reallly good catching up and sorting my electrics out once and for all! (Just have to sort out these other bloody problems first if I can't find a trailer...  Cheers again, Den.
