    I have 5,000 miles on my 2012 Tacoma, and I've noticed that when Im idling at a light, I will sometimes see the RPMs increase a little bit for like 5 seconds, and then return back to normal. If I don't have my foot "firmly" on the brake, I will actually move forward a little. Is this common? Am I just too light on the brake? Any advice would be appreciated.

    AC isn't on...I would say the increase is from 500 RPM to like 800 RPM...

    Your AC will engage whether it's on or not. The lurch you feel is the tranny down shifting into first.

    does it do it more when cold? see if it happens when you slightly turn the wheel. as soon as there is any sort of pull on the power steering your rpm will bump up a bit.

    LOL...no, just a slight increase while idling...Im new to Toyota, and I feel like the brakes are kinda mushy. My bro has a Tacoma too, and he thinks the same thing. Maybe its more of getting used to the brakes (putting more pressure on them) than anything else???

    Really sounds like the defrost is on. Defroster will cause A/C compressor to run.

    What model is it? My 07 does that at the light sometimes. I never noticed any increase in rpm's though. I was told it is the LSD engaging. :confused:

    I have the same thing. At first I thought someone was nudging me from behind, even though I felt no impact, the truck lurched forward ever so slightly. Now I just lay into the brake when I'm stopped.

    If you turn the fan on with the vents set to Windshield or Windshield + Floor, it will cause your A/C compressor to run, also causing the ECU to bump your RPM a little bit to compensate.

    This happened in the first week I got my truck. It happened at night and I was at a set of train tracks waiting for the train to pass. I had thought that the truck behind me had rolled into me, we were on a small hill. I pulled over and checked after and nothing. It doesn't from time to time and mostly I don't notice. A weird feeling if you weren't use to it that's for sure.

    It's normal man. My 06 did it, and my 09 does it. It still gets me sometimes. Lol like mentioned before, its either the compressors or torque converter since I've noticed with the A/C on and off.

    Next time you are at a light take your hands off the wheel and see what happens.

    Every Toyota I have owned has done this, starting with my 99 Camry. It's a Toyota thing...you'll learn to love it...
