Rough Idle Only When Warm 200

I have a rough idle problem that started about a week ago. I have since replaced the accordion hose (it had several small holes on the inside (away from the strut tower)). I have also tried to finad any other vacuum leaks with no luck. The problem only seems to occur when the car is nice and toasty warm -after about 30 minutes of driving. I unplegged the AMM and the only difference I could tell was the light on the dash started blinking. I suspect the AMM is starting to fail (maybe because of the 5-6 small (pinhole size) holes I found in the accordion hose. I checked the FAQ. That's the only thing I can figure.

Any help or comments are greatly appreciated.

Todd :-)
