Engine revs while moving slow/brake engaged

Hi,
I’ve noticed several times that when moving slowly ie. in a drive thru that the truck will rev/accelerate on its own. Anyone else have this problem? Fix’s?

 

Pressure sensor on the power steering pump or AC cycling. It's normal. You'll get used to it.

 

It's from you moving the steering wheel. First time I noticed it was waiting to turn right at a light. Thought the person behind me bumped me.

 

Yeah, to echo everyone above, it's normal. But it sure surprised me when I nearly lurched into the back of my garage. Once you get used to it you'll probably account for it in your driving habits and forget about it completely.

 

Mhm. I was sitting in the school parking lot waiting for my dumb twin brother to get out of school and I happened to turn my steering wheel which caused the engine to slightly rev, and the guy next to me heard it ( he was in a mustang) and started revving his engine for absolutely no reason and we both got in trouble.

 

Mine does it..especially before the engine has fully warmed up..a cold surge. No steering input. The latest TSB seems have mostly cured it.

 

Thanks for the responses y’all.

 

I was gonna say the first time I drove my 21 SR to work just easing into my parking spot and it did the surge thing almost sent me over the parking block

 

Normal, but there's something to be said for Toyota's poor idle management programming. My first gen never did this
