  • Hi, I have a 2000 Toyota Tacoma with 106K miles that usually begins to shake and vibrate when it(the engine) is cold, usually in the mornings, and when it is not moving. I have no idea of what might be wrong with it or what causes it to shake. I would really appreciate it if y'all can tell what might be causing this.
  • I am getting my 2012 back from the dealer in a couple of hours from having the same problem looked at. The service dept. took the intake off my truck, took the valve cover off, checked and micrometered every thing and can find nothing wrong. I first noticed and fussed about a slight ticking at a couple thousand miles. It has gotten louder as time has gone on, so at 8300 miles, I had the dealer check it out. Now that they tell me they can find nothing wrong, I am more baffled than before. The dealer pulled a new 2013 truck with less than 10 miles on it in beside mine. It makes the same ticking noise. Crazy!

    It sounds like you have a bad EGR valve and there some issue with your engine I would bring that puppy back to toyota with 4,500 miles on the board and let them go thru it do not waste time or it could come unglued and check your oil to make sure you do not blow it with low oil or none see your toyota people a.s.a.p
