It took me a long time, and some help to figure out that my AMM was bad which led to a poor idle. Now that I've gotten a replacement AMM I learned that it would be wise to replace the air box thermostat. Now that the air box is lying on my work bench,and a new thermostat came in the mail today, I cannot figuure out how the darn thing (or assembly) comes off/apart. I'm afraid to yank on it, cause the assembly is made of plastic. Secondly, in looking at the Bentley book, it says to check the operation of the thermostat at different temperatures which range from about 40 to 60 deg. F. So I ran the new one under the kitchen sink with a tape measure against the operating rod and couldn't detect any movement. I'm going to do battle with this later tonite, so any help would be greatly appreciated. I must be missing something. TIA
