No "check engine" light, but it would always stall about a mile away from my house. It turned out to be a weak temperature sensor for the fuel injection system - about US$5 and readily available at most car parts stores. It is on the firewall side of the engine and a bit obscured. The temperature sensor on your friend's car might be malfunctioning in the opposite mode, which would cause the fuel injection to run rich (in keeping with the flooding and poor fuel economy) because it thinks the engine is cold. Keep in mind that this is a separate sensor than the easy to access one for the instrument panel temperature gage, and these sensors have different part numbers and electrical connectors. Good luck.
