The car's engine started shaking at idle about two weeks ago. In the beginning it was intermittent. Then it would shake at idle everytime. I replaced plugs and wires. That helped but some shaking was still there, it could be felt when the car was parked or stopped at a light. It was almost imperceptible when driving. But there was another problem associated with it: low power. When accelerating the engine revved up but acceleration was very slow. If I floored it from a standstill it accelerated fine to 40 MPH (that's when I decided to end that test) but if it was already rolling the engine would rev up to anywhere between 3000 to 5000 RPM (depending on how hard I would press gas) before changing gears at about 25 MPH. Similar thing happened when accelerating to highway speeds and I would end up going at 60 MPH with the engine running at 2500 RPM (or is that normal?) I took it to Auto Zone and got a reading. The error was P0305 cylinder misfire, #5. What would be the next thing for me to do in order to fix this problem? Thank you.

PS. I don't know if it matters or not but the car had the timing belt and water pump replaced about three moths ago. Also replaced were the intake manifold gaskets because of oil leaks.

 

Yo what's up? I have the 2001 millenia s and I had the same problem. Even though we have different engines I believe the code means u have a bad ignition coil if your engine uses those.I have had 2 change my car's ignition coils twice since I had it and I had it since october of 07. Also there is a web site 2 see what your codes mean. Let me check and get back 2 u on dat.
