Problem Description and Possible Solution
A dirty throttle body may cause low engine idle speed or frequent stalling, as oily residue blocks air flow in the throttle when the throttle is closed. Throttle body cleaning may be necessary to correct this condition. Our technicians caution against spraying cleaner directly onto the throttle body as this may damage the throttle position sensor (TPS).

Problem only happens after van is warmed up. Low engine idle causing oil light to flash or stay on, also get the dinging warning bell. This stops once I accelerate. Was told to try changing the Throttle Positioning Sensor. Haven't tried yet.
Changed TPS, worked ok for about a week. Now it's begining to stall again when sitting at red light or stop sign. Usually starts up right away, but sometimes have to keep trying while holding up traffic.
