Why does my Ford Ranger keep stalling?

I recently bought a used Ford Ranger and it keeps stalling while I'm driving. I've checked the fuel pump and spark plugs, but everything seems to be working fine. What could be causing this issue and how can I fix it?

It could be an issue with the fuel injectors. I suggest getting them checked and cleaned if needed. Also, make sure the throttle body and air filter are clean.

Another possibility is a faulty ignition control module. This can cause erratic engine behavior and stalling. Have a mechanic check it out.

Check the idle air control valve as well. If it's dirty or malfunctioning, it can cause stalling. Cleaning or replacing it might solve the issue.
