I have an 05 Sonata GL with a 2.4 liter engine manual transmission. Anyways I was driving down the highway today and the check engine light turned on and the tach started bouncing all over the place, when idle at a light the tach shows 0 RPM'S. I pulled the code and it came up with P0320. I had looked under the hood to see if anything came loose. Everything looked fine I then stared the car back up and the tach worked normally again. After letting the car sit for a while I start the car again and once again the tach is going crazy bouncing all over the place. It seems like once I start the car up after it's been running for some time and its warmed up everything works fine. Somebody was saying it may be the Camshaft sensor or and ignition coil. Any ideas what it could be?

By the way I bought the car used from a Hyundai dealer last summer and my warranty is gone now that I'm at 63k. I'm hoping it's an easy fix
