my 2003 honda odyssey is surging when at idle and the check engine and tcs lights
 

are on.? the van has 112,000 miles and has recently had the timing belt replaced.

trash it.

Take it to and Advance auto or Auto Zone. They will run a diagnostics check on it for free. Probably just a sensor.

take it to autozone (oriley or other auto part stores might have the same deal) and have them hook up their computer to it. they will tell you why the light is on for free.

well a good idea, since the check engine light is on, would be to take it to the dealer. Since your on yahoo answers looking for help, you obviously can't figure it out on your own, which mean you probably can't fix it on your own.































With it having that many miles on it, and it being a minivan, you probably have a family of 4 at least and it is there primary mode of transportation. Don't **** it up trying to be Robert Yates or Carrol Shelby, take it to the dealer pay them to professionaly fix it and keep your family safe.
