It seems to be running fine. Sometimes when I'm sitting still it's rough and l notice when I turn on the fan (a/c or heat) it idles rough.

Thank you. If all of those components have been replaced then you more than likely need to replace the timing belt or it may just be a bad crank position sensor sending the wrong signal. If the timing belt is worn out then this will occur.
