From the very beginning of this post, I had this sneaking feeling that it just might be as simple as richinning the lsn by 16th turns until the problem disappears. Of course, I'm sure that Site Jester is the authority on this mater, not to mention, others. He owns sts, where as, my opinion is based on tuning my 4.6. If all else fails, give this a try. It won't take more than a quick warmup to find out. I take it that the motor DOES idle ok and does'nt seem to be running fast. If it is running fast, this supports my feeling about this issue. Tell Site Gester what fuel and nitro content you're using. So, as you begin, your truck should'nt be trying to drive away for while idling for example. As you richen the lsn, your idle speed may drop abit, so blip up your idle startpoint at your TX enough to prevent any stalling when idling. You may need to do this more than once. Also, reset your idle screw each time you make your blip adjustments to where your motor is now idling at the time. This prevents unwanted idle drop and also takes the load off your servo, saving some battery life. Just remember, 16th turns, Joe.
