It starts up fine and will idle smoothly but will start to lope like it wants to stall and it eventually does. Also has a tendency to stall out when I have to stop at a light or stop sign. And if take a turn kinda slow it will stall. It's always started back sometimes it takes longer than others

Scan for codes and check fuel pressure first. Check for blown tbi gasket by spraying choke cleanr all around it if rpm changes then replace gasket. And check hose leading to map sensor for softness and sucking together
