You will be able to tell if it is Federal or California by the underhood emissions sticker. Post of pic at bottom with the important area pointed at with arrow. Should read "This vehicle conforms to U.S. EPA regulations applicable to gasoline fueled....yada yada." If anywhere in that context it says including the state of California then it is a California emissions. If it only says Federal or non-green state then it would be Federal. The Federal emissions only has one converter in the exhaust about half way down the van. The California has warm up converters in both side exhaust manifolds as well as the one in the Federal emissions van. Take a look and see if you can tell from that.

I have a 2000 MPV that just started idling very rough and it also seems to run a little rough at a constant speed. I got Autozone to pull the codes and here they are:

P1170 Fuel Air Metering manufacture control
P1173 System too lean Bank 1
P1171 System too lean Bank 2
P1520 Manufacture vehicle speed control
P0300 Multiple cylinder misfire

I suspect one component is causing all these codes. Does anyone know which component it is?
