My Montana started sputtering, but hasn't died, what's wrong? I got my oil changed, and the guy said it wasn't the engine. My 'Service Engine Soon' light is flashing when I drive.

    I'm a girl so I don't know, but is that like the Oxygen sensor?

    Had it scanned it's the spark plugs and wires, so we'll see I may be asking for help for my husband changing them!

Car sputtered to a stop. Rpm ran down to zero and died.

Doubt it had anything to do with the oil change or belts replacement unless they were done wrong. e.g. improper oil or belt placement. Sputtering, as you stated usually comes from the fuel system. Check that.

see if the cam is turning when trying to start the engine (look through the oil filler cap) if its not, you may have a broken timing belt (and engine damage) if it wasn't empty on the fuel gauge I doubt it ran out of gas.

2001 montana "service engine soon"

Hello and welcome to FixYa!

This warning serves as like a maintenance warning. It can just be a simple oil and filter change. Not a big deal but definitely you need to have an oil change.

Hope this helps and thank you for using FixYa! Have a good one!
