This car often has problems starting. If I hold down the gas a little it will not stall on start, or will actually start and run. Often when the car is running fine it will just stall, usually at speeds between 15-30 miles an hour. The ECM was recently replaced and it solved a lot of other problems the car had (non-functioning speedometer, check engine light) but the occasional stalling problem continues.

Welcome to the forum, thanks for the donation. I'd use a gage and check fuel pressure, 34-40psi-mfi. Take the throttle-body off and give it a cleaning. Any codes? Originally, they had so much trouble with the maf sensor on these that they converted to speed density system. I've seen this vehicle with and without the conversion.
