Hello,

1995 Lumina 3.1, 105,000 miles.....
Recently this car has begun to stall at low rpms (coasting, red lights,
turns, etc.) It also "lopes" or "surges" when coasting. Never a problem to recrank after a stall. These problems have only happened after the car has warmed up. Recently installed new plugs, PCV, air filter and fuel filter. Any suggestions would be helpful. Thanks.

1. Is the check engine light coming on? If so, take it to autozone and have the codes read and post them back here.

2. Check for any disconnected vacuum lines.

3. Have someone test the EGR valve. It could be malfunctioning and causing your problems.

Or, it could be a bad IAC motor, Torque Converter Clutch Solenoid, MAF sensor...etc. etc.

Get those codes read first before you start blindly throwing money at it.

you did a lot of work. Did it happen after you did one particular job?
Make sure you didn't knock off a vacuum hose
