Car keeps turning off!?!? CAR TROUBLE,HELP PLEASE!?

Sounds like an intermittent connection. I would start by having the battery terminals cleaned and tightened. The see how the car does.

A vacuum leak can cause this. It could come from a bad vacuum hose, cheap to fix, or many other expensive defects, such as a leaking manifold. Somebody who knows what to look for will be able to discover the actual problem by examining the car and none of us in this forum are him. Hold it up there in the light... I can't see it at all. Shine that light over to the left... no,I still can't see it at all.

This all began once you replaced the Mass air circulate sensor perfect? Did you circulate purchase a clean one from Nissian, or get a rebuilt one from a areas homestead , or did you circulate to a junk backyard and get a "used " one? in case you probably did the final one to procure the incorrect one the black smoke is an illustration of thank you to plenty gas contained in the combustion chambers , the Mass air circulate sensor senses the quantity of air it quite is getting to the engine and tell the ecm to the two richen or lean the mixture like the O2 it facilitates administration the gas mixture the o2 tells the ecm how plenty air is present after Combustion tha Mass air tells it how plenty gas is would desire to run the engine. the incorrect mass air can unquestionably supply the ECM fake info ensuing in you guessed it black smoke.

ok um so...it shuts off after the engine warms up right? check your igntion control modual...fords are know to do that if the ICM is going out

crank sensor sounds more likely

fix the vacuum leak first.
