No fast idle on hot start, plugs fouling????

Title says it. When hot plugs have been fouling regularly. Only thing I've noticed is no fast idle on startup when engines warm. revs to 3k when cold start for the 17 sec's as norm. What might kick out when hot to prevent that? I feel it might be lack of bypass air causing the fouling. What should I check.
Thanks in advance.

Fouling plugs can be caused by dirty injectors. That's what happened to me.

There should be no fast idle when the enigne is hot, because it's not needed. The AWS (accelerated warmup system) is there to warm up the pre-cat faster, and only happens when the engine is completely cold.

Whatevers' causing the plugs to foul, it's not this.
