1997 Chrysler Town & Country LX with 3.8 v6. How does the computer meter the air that goes into the engine? I don't see a MAF sensor, so is this use a speed-density system to meter the air? I believe that this is the reason why my mom's van occasionally stalls. It will always start back up, but it stalls intermittently, usually at low engine speed. There does not appear to be any vacuum leaks, the check engine light is NOT on, and it runs like a champ. I know this does not have a fuel return line, so obviously the computer controls the fuel pump to regulate fuel flow. Any ideas of what and where to start with?
