Throttles keep going to 20%

[Guest Sticks]

Hi Gang,I have the 736/7/8/900 and am experiencing something odd I didn't experience with the 737/6/7. I installed the 738/9At the other night. After setting the throttles and about 10 seconds in the roll the throttles kick back to 20%. This happens w/ and w/o using the FMC, A/T or the T/GA and occurs during approach as well. All systems appear to be set and normal. Another oddity, the Air Conidtion caution light keeps coming on about every 15 min.I have the update 3.0 installed.Any ideas what may be casuing this?ThanksBill

Hi Bill:About the air conditioning warning: I have experienced the same.When that happens, I check the air-cond temperature in the overhead panel. It seems that when it reaches 22

Thanks Jose, I did that prior to posting but apparently didn't leave them in the setting long enough.Now if I could figure this throttle thing out I'll be good-to-go. I checked my equipm't and everything is working and rock solid.ThanksBill
