Hi - I have a 1999 Alero, The check engine light came on about 2 weeks ago. After I continued driving it started to stall when the RPM came below 1000.
Checking under the hood I found that disconnecting the PCV valve from the suction allowed the engine to idle ok. I replaced the PCV Valve started the car and it stalled. I am at a loss on what could be causing this Please Help!!! Thanks
