When i hit the throttle the engin bogs down and shuts off

Replace the fuel injector system. When you shut it off, the fuel continues to dump in the cylinders. This is the reason you have to open the throttle and rev the engine up. Getting rid of excess fuel.

you must be putting out a boat load of codes what are they

I replaced the resister to the blower and now it works

check the fuel regulator and fuel pump. also check the filter for the fuel.

is there a rattle under the car like the cat converter is bad when was the fuel filter last replaced

check the air flow meter operation and rangeing

there are several possibilities. by bogging down do you mean the engine runs smooth but looses power? or does the engine/car start shaking and doesnt want to go any faster? if the engine runs smooth and doesnt seem to be shaking...can you hear a noise from the engine compartment? or a hi pressure noise from the rear of the vehicle - like a vacuum cleaner? if so then you probably have a plugged catalytic converter. if the engine seems to shake the van and looses power until you let up on the throttle slightly then you have a misfiring condition which can be caused by bad plug wires,plugs or a coil breaking down. as you shift up in gears the spark needed to each cylinder is increased and if you have bad plugs,wires or coil the spark wont get to the cylinder when it is needed. see if any of this sounds similar to your condition and request more info from me if ya like. good luck. carefull the converter can cause a fire if it gets too hot!

First replace the fuel filter.

repair or, replace the MAP flap switch on your engine's intake tube this switch measures the air volume admitted into the engine so that the engine computer can adjust timing and, fuel injector speed.

next time it happens try spraying water in mist form around the throttle body if it bogs, replace the throttle body gasket. if it doesn't bog you may have a bad wire wait until dark start the vehicle have someone feed the fuel very slowly and watch for arching from a wire it will be easy to see when it is dark, replace that wire.
