I been having a problem for some time . Where my idle jumps from 1500 to 650 and then the car stalls out. When i start it it seems to be okay for a little while thens it stalls out again i have no ses light i wonder if it can be a sensor if so which one.
Thank You

 

Check your Idle Air Control Valve. Looking at the front of the motor it's on the left side of the throttle body underneath the TPS. You may need to remove and clean that sensor.
