Hello all, newbie here with a question.

I have a 2004 Tacoma with the 2.4L and manual transmission. I got the truck used with 69,000 and it now has 127,000. Within the past couple of days at around 25 MPH in 2nd gear (I dont have a tach, so its hard to say at how many RPMs), it shakes back and fourth (just like when you are stopped and you let the clutch out too fast and it jerks back and fourth) and has a weird vibration. Once the RPM's get higher, it goes away. I've only noticed it in 2nd. I noticed it more today as I was driving home from work.

Just for more information (in case it could be related), the other day I came to a stop, and I noticed the engine was idling much higher than normal. It wasn't obnoxious by any means, but it was enough to make me raise an eye brow. it hasn't done it since then though.

So, if anyone may know of anything or anything I can try it would be nice.

Thank you.
