If it looks like a James Bond movie, you have a blown headgasket

SOURCE: large amount of white smoke on first start of the day

Have you had the injector recall check carried out? There is a problem with these injectors and this produces the symptoms you are describing. I suggest that you contact Isuzu direct for help. They have been very helpful in the case of my trooper

SOURCE: white smoke coming from exhaust when accelerating

This is usually an indication of a bad head gasket.I gasket. The white smoke is the coolant leaking out of the engine and winding up in the oil passages, due to a bad head gasket. To confirm this,
1. check oil. Is level increased, or milky appearance?
2. Is coolant level dropping, but u don't see any signs of leaks?
The above indicates a bad head gasket, causing the white smoke u describe. Let me know how u make out.

SOURCE: not accelerating and letting white smoke out exhaust

it sounds like the engine coolant is leaking into the combustion chambers most likely due to a leaky head gasket or a cracked cylinder head and will cause loose of power in acceleration
