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).Google+

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.

I have described this problem to my mechanic but he couldn't duplicate the problem so it not fixed. When it stalls or starts to stall the oil lamp comes on.
