Car idles and runs fine when cold, but when at operating temp. And coming to a stop the idle rpms fall and the engine will nearly die, then recover and idle ok until the next stop. It occasionally dies and restarts ok. This happens while car is in drive gear. If I put it in neutral when stopping, idle remains ok. A scan revealed only a Vehicle Speed Sensor code set. I checked, cleaned the EGR and it opens and closes with a good snap with vacuum applied, but don't know about the EGR modulator function or possible IAC problem, too. Can VSS affect idle, etc. Or?
have the same problem?
