I have a 2003 Accord, 2.4L engine, it has been idling pretty bad. It will start, once running RPM will be below 750 and loses power when i get to a stop light. Now when I turn on the A/C, the RPM will fall to 500 and the engine starts to shake pretty bad. I too it to a mechanic, but he's not sure what's wrong!!

Hello,

Is your check engine light on? Have you had it scanned for codes?

When was the last time the engine was tuned?

You might find this article helpful, it covers how to check for vacuum leak:
