Have another little problem with my 280zx,

It keeps on stalling on me, driving along come to a stop at traffic lights or to slow down for a turn and the car keeps stalling,

It seems to run just fine, i have replaced plugs, leads and coil, re-set the timing to 14deg, it started a day or two ago,

What causes a car to just stall?

Fuel pressure? Just a thought, because stalling is far more often caused by fuel than ignition.

Question , does the engine just quit like you turned off the ignition ? Or does it stumble some like it is running out of fuel ? Gary

Car stumbles slightly, but that may be it just stalling, its reving at 900-1000rpm, then just stalls, Radio starts to flicker, than it just dies - the idle however is not rough at all, its idling at 900-1000rpm or so, than just dies on me,

I say the radio, but also the lights (when they are turned on), its like it just loses power, but it has re-started 1st time every time after it stalls without the slightest drama,

But, it also is starting to happen when im driving now, last night i was going about 70-80km's and it almost stalled on me again,

The Radio started to flicker (thats my early warning signal) and the engine started to die on me, i quickly reved it and avoided stalling,

Dont know if this will help, but when i start the car (its an auto) it sometimes dosent start when in park, i have to put the car in neutral to start the car, in park it makes an awful grinding noise, i change into neutral and then it starts fine,

Just seems to idle and drive fine, but then for no reason the car just dies, the only warning i get is the radio flickering or the lights flickering, you cant really here anything noticeable in the engine,

Sounds like you got poltergeists. Seriously though, the stalling and the grinding tranny are probably two seperate issues. Anyone else think this stalling issue might be a bad or loose connection at the voltage regulator, or a bad regulator?

The tranny issue sounds like you've got some bent or out of adjustment shift linkage. Not sure though as I've never seen an auto Z tranny before.

Hmmmm,

I don't know about poltergeists, but losing the radio and the engine carking it certainly sounds like you have a UFO following you.

Seriously, you say it sometimes won't start in PARK, but does in NEUTRAL.

With my 260, I always check that the shifter is FULLY forward before turning the key. If it's only a couple of millimeters off full forward, it won't start. There's no grinding noise though.

Is it every time you come to a stop or say only when the blinker is turned on? The reason I ask, maybe there is an electrical short in the system.

Car-sar-nit, Poltergeists you say!!!

Nah, it dosent really seem to be affected when i turn the lights on or off, or whether the indicators are being used, or anything eles for that matter,

Interestingly though, it has sorted stopped doing it, it might only be doing it when the gas tank gets below a 1/4 full - thats what appears to be happening at any rate,

With the transmission, the guy i purchased it from said there was a problem with the cut-out switch, you know how you cant start an auto car in anything but Park, that switch that makes it so this actually happens is faulty according to the guy we bought it off, but why the grinding noise???

The grinding noise is probably the Starter. At least I hope it is as my 260 has just started doing the same and I'm suspecting it's the bushes in the motor?

As for your other problem, I'd be checking the battery terminals, aternator leads etc.
