Don't know what year you have but some sensors are temperature sensitive and you should run a 195 degree thermostat.

There is one before and one after the catalytic converter.
The fuel lines around the filter; you will need an adapter.
There is no adjustment required, but you can clean it with a carb cleaner.
Use an exhaust made for an LT1 engine the blocks are identical it is the insides that is different. Will bolt right on.
It should be on the front of the intake manifold directly above and behind the water pump.
Several possabilities. One is a bad PCV valve if it leads to that bank of cyl. Another is the intake gasket for that side of the engine. Worst case, but not likely as it is affecting all of the cyl, is a failed head gasket. One question, are the plugs fouling with fuel or oil? If over fueling, it could also be an injector or injector wireing issue. Could it also be bad oxygen sensors? If there are four oxygen sensors on this van, and the one for the right bank of cylinders is giving the wrong reading, that could cause this problem. Seems unlikely, though.
