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.
Stalling at low speed or idle. Was told dirty throttle body.
Same problem and haven't been able to remedy it as of yet
rough idle while in gear. stalls out when stopped at red light or stop sign. I have replaced egr valve idle air valve plugs and wires and cant find a vacuum leak.
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.
