you sure you have all the earths on under the bonnet and inside the car.
What i do is weld a nut to the chassis and then use bigger ring termials on the ends of the wires that need to be earthed and use a larger bolt to hold them in place 100%.
The earth by the front headlights and also by the wiper motor are always shite! Dont just look at them and say they look ok, cut the terminals off and solder new ones on.
There are only around 6 earths connected to the loom, check each one. Also upgrade the connections if you want to fix your problem/s
