    I found out the Problem is with ECU or PCM which is located uder the Dashboard on the right hand side of the Vehical . Some water gets into it and damages the engine Timing and hence i suppose it gives out white smoke .

If your sprayin the underbelly of your rig, the water on the outside catalytic converter is producing moisture on the inside of the catalytic converter. Nothing to worry about. Just annoying. In time it will cause your converter to rust trhough like all the others do.

Hope this helps.

I am losing antifreeze no leaks and white smoke

White smoke means the car is burning antifreeze, along with gas. One of your head gaskets has blown out and will have to be replaced. Also the cause for overheating. A block test or compression test will confirm it, and tell you which head gasket is out, whether left bank or right bank of engine.
Sorry for the bad news, ft, cylinder head repairs are expensive.

Sir, My ford windstar 1998 give me the code P0174,sytem too lean(bank2), can you tell me what the problem is , it gives a heavy white smoke when i start the engine . just put a new cylinder head gasket...

It's an intake gasket. Another option, however rare is the air flow meter. But not likely. The white smoke is most likely antifreeze leaking into either a cylinder, or the intake and entering a cylinder, exiting as white smoke. The bad intake gasket (or intake manifold) could be causing both problems. I'd try a new set of gaskets and just the upper half of the intake manifold.
