2JZ-GE - rough idle, white smoke, catalytic converter light on

[msupra1]

I'm asking this for a buddy,

 

He picked up a 1994 NA 5-speed 4 months ago. It's only got 92,000 KMs (57k miles)

It's been mostly sitting and just started up to be moved. Mentioned that it was running fine when he first got it.

 

After starting it up recently, he described the motor was running rough and shaking.

 

He started it up again recently, it has a really rough idle, it's shooting a lot of white smoke, and the catalytic converter light went on after the car warmed up for a few minutes. Also described that the smoke has a deep burning smell to it.

 

 

Not too sure about these 2JZ-GE motors, so any idea's? could the spark plugs be done and it's not running on all cylinders? or what else is a common problem?

 

 

Regards

Reset ecu by taking battery off for ten minute and check for water round the spark plugs bit hark I no as there's an inlet manifold in the way but rough idle and hard to build up rev is a sign of water round the plugs, has he washed under the bonnet recently?
