Starts every time then stops after about seven seconds every time. Runs great when revs are about 1800 or higher. Have checked air flow meter resistances and all are good. Ignition coil is good.
Are their any codes either stored or open might be a fuel supply issue is it starving out or just stopping if just stopping check all related fuses if starving for fuel check fuel lines fuel filter back to the fuel pump. also it could be an injector issye

Change all the filters (fuel and air). check and see if all your spark plugs are firing or just change them. if it is fuel injected make sure your injectors are working. Hope something there helps get it running good.
SOURCE: running lean at idle & rough idle stalling.
Replace the fuel filter,have the fuel pressure check,it is most likely the fuel pump.

your throttle position sensor is maybe causing an overfuel,or the egr is plugged and when you rev it up,it is not burning the excess.if you leave it like that,the excess unburnt fuel will burn out your catalytic converter

I ahve same issue with my 2004 MPV. I replaced the plugs, coils etc. No help.
did you ever get it fixed?

could have water in your oil for the smoke but try to change the plugs first and plug wires for a little tune up and also after that if no changes then you might need to try changing coils or coil pack whichever one your vehicle has
