AutoZone ran a tester on my vehicle and said it was bad mass airflow sensor, made sure that was good, cleaned it, and put it back. Then I pulled the EGR valve out along with the EGR vacuum solenoid, cleaned both, made sure the valve was working. Then put in new EGR vacuum solenoid.

My vehicle was still acting up, so I put in a new EGR regulator. It still was stalling. So I put in a new fuel filter. I don't know how to do a vacuum test to see where the vacuum leak is at. My question is, what else could it be? I have spent all my time and money trying to find the problem? Can't afford the expenses of a mechanic. Do you have any suggestions?

Good evening,

Can we start with the codes? Autozone sells parts. They are not technicians.

Did you clean the throttle body? That is a common issue for stalling.

Once I get the codes, I can narrow the area of failure for you. In most cases, it is a throttle body full of carbon.
