I have a 2000 chevy impala 3.4, w/over 200,000 ml. I ran out of gas 1 day, and after I fueled it it wouldn't start, fuel pump was dead, replaced that, and after that the car kept stalling, took it back, need water pump, still the same problem, check engine light indicated that it was an airflow sensor problem, so I replaced that as well. Still my car stalls, cut off when I stop at a stop light, as well as getting off the expressway, or making a turn. Can u help me please!
Do you

That's not a MAF code at all. That is a lean code that could be due to any number of things. The first thing I would be looking for is a vacuum leak or air leak from the intake snorkel.

Click on the thumbnail and it will enlarge. This is the procedure a tech has to follow to eliminate all possible causes. You may not be equipped to do it though.

The site won't allow anything larger. You'll have to save it and enlarge it on your PC.

Did you check your fuel press valve?
When you pull the vacuum tube on it, if fuel comes out. Your engine drowns
