5th issue is an ABS light - If you have done all the checks for the sensors and the rings are all good then it could be the ABS ECU. This fails because of the heat soak from the manifolds drying out the soldered joints inside the module. There are companies that will repair them, I posted on the forum about the one I used a while ago.
8th issue is a slack throttle cable and a rough feel under operation. - The OE throttle cable is not great and no amount of oiling will solved the notchy feel. I highly recommend you build yourself a new one from a universal aftermarket manufacturer. Again there are lots of posted about it on the forum!
