My car idles quite randomly, when the engine warms up it idles at 1, 2k rpms, when it is cold it idles at 800 and also it slightly fluctuates.
What could be the problem to that?

I also wanted to change the fuel filter however I can't seem to locate it, I don't have the manual to the car also making it more difficult.

Hello,

This sounds like you could have a vacuum leak somewhere on your vehicle's engine somewhere. Here is a link below for you to go to below, but I would pay special attention to the intake manifold. A lot of vacuum leaks occur right there. Here's the link:

Please go through the guide and get back to us with what you are able to find out.

Thanks,
