Just be assured that this is a common problem with AS kids. My son would growl, too. Just remember too that negative consequences don't work very well. Unfortunately, sending him to his room is not going to deter him from doing this again. The best thing to do is to foresee issues and head them off.
"I see you forgot that it is rude to go to our neighbor's doors. How can you remember next time?" If you explain the rules to him in a way he will agree, it usually will work. Most of these kids do not want to be rude, but have no idea what 'rude' is! Letting him know this is not a socially accepted thing is something he can add to his 'database' of social knowledge.

I try to diffuse the situation with my son by stopping what is going on and asking him to name his emotions and explain to me why he is feeling that way. Then we go through ways to help calm down. Sometimes he needs to be squeezed other times he needs to be alone to calm down. There is usually a lot of crying but I do all I can to make him feel better while still holding steady on consequences for unacceptable behavior.

What kinds of things help him feel calmer? I created an "INH" box (I Need Help box) for Ellie with all kinds of sensory things in it. I included food that was crunchy, sweet, sour, chewy, etc. as well as gum, some squishy toys, a weighted snake toy, a homemade "find it" toy (a empty 20 oz soda bottle filled with dry rice and tiny things to find in the rice), and pen and paper for drawing. Other ideas might be a blanket, something that is particularly interesting to your son. The trick is to have him help with things to put in there, and to PRACTICE and see which strategies and items help him feel various ways. It's hard for my daughter to access what she knows when she is in the middle of a meltdown, and she destroys her share of property, as well as hurting people, but it is a start, anyway.

Behavior modification therapy? Anger management therapy? These work for us. It's hard living with an ASD person, but it's harder for the person who has it. Especially a super bright boy with changing hormones.

My daughter has high-functioning autism and she had the same type of issues when she turned 10. She also started her period that summer which seemed to add tons of fuel to her temper fire. We tried all of the suggestions for the lists like you have - the counting to 10, etc. and nothing worked. We tried time out at school and she was still picking up chairs and throwing them or anything she could get her hands on. The bad thing was, there was usually no warning that she was getting ready to have a blow-up. Sometimes you could see and sometimes you couldn't. She's now 5'3" and around 135 lbs. so controlling her is difficult - plus she is much stronger when she's upset. We had never considered medicine for her at all before but at this point we had to. Last year she was put on Topomax first and then Risperdal along with it. We didn't like the fact that Risperdal is for seizures (she has none) and also for schizophrenia but it was approved for use with autistic children I think back in 1998 to control anger/temper tantrums and blow-ups. It has worked well with her except for the side effect of causing her to slow way down(she used to be full of energy, running around, riding her bike, scooter, etc.) and has caused her to gain weight - probably about 15 lbs. This is not only from the inactivity but the Risperdal causes an increase in appetite also. So a few weeks ago we went back to the doctor and she prescribed the anti-depressant, Fluvoxamine, which was given slowly while weaning her from the Risperdal. She seems to be doing ok but has been having one big outburst a day. We are hoping this doesn't increase as time goes on because we can't have her hurting others or herself. I have been reading on this site about a drug some parents have said has worked with their children called Tenex. We might have to check into this one if the Fluvoxamine doesn't help her as much as we need it to. I don't know if you are medicating your child already but if not there is definitely a time a place - you will know when that point comes - where something has to be done and medication may have to be an option for your child. Good luck with whatever you do! Take care.
