Car Juddering on start up
 

My car seems to be a little sick but I am not to sure what it is?


On a cold start it judders. I have got out and looked and the exhaust is moving and white smoke is coming out. A rev normally fixes this. After about 30 seconds the juddering stops and no more white smoke and it drives fine.

Now I have checked under the oil cap and there is no white sludge, water tank water is still pink and filled up, but I think it has lost some. I only filled it up today and it has not lost any power. Its not over heating either. So I am ruling the head gasket out for now.

But I am stumped. I have a few idea on what it may be but please tell me if I am wrong.

Fuse plugs?
Bad fuel?
MAF sensor
Starter motor
Battery
Timing belt out (Had it changed a year ago)
Head gasket (Although I dont think its this)
Injectors
Sticky valves

And a worse one taken about an hour ago.

This had been running about 10 minutes. Its pouring down. Previously to this I had to use it for about 45 minutes about an hour previously.

Temp gauge had gone up and down a bit. Never to full. But rested at half. Car again lost no power. Smoke suddenly stopped then.

Anyone have a clue?

Water in the exhaust pipe vapourising?

Water in the fuel?

Have you driven in very wet conditions lately?

Check that the air filter is bone dry.

The sparks are coming out tomorrow to see if they are in poor condition/covered in oil (Hope not) or any other issue.
