you've given us nothing to go on.
P300 is a generic misfire code. What scanner or diagnostic equip are you using to come up with that code? There should be P030X codes to go with where X is/are the cylinders that are misfiring.

P0300 is random multiple misfire. It's the code the devil himself uses, as it tells you absolutely nothing, besides that there is something screwed up.
Whenever I get that piece of demonic diagnosis, I start by looking at what links all the cylinders together.
If your scanner is up to it, a nice feature is to test each cylinder for rough running.

My apologies. I used the innova scanner. My cluster gives me restricted performance and it smells like there are some unburned fuel. It's on a limp mode when it happened. Thanks in advance

BTW, i was told that it could just be the camshaft position sensor or coil pack. I would like to try and replace the sensor if you can tell me where is it located at? I've searched the web but i did not find anything specific with RRS. Thanks

The camshaft position sensors are installed in each cylinder head at the rear of the intake camshaft. It is a variable reluctance
sensor that provides an input to the ECM regarding the position of the camshaft.
