The Grounds that should be addressed are the ones for the ECU. The ones on pins 2C, 2R,3A, 3G.
And for the very last time: Its pin 2C (ECU ground), that is the important one to concentrate on. Look at your EGI EMISSION CONTROL SYSTEM Schematic sometime. Find pin 2C. Follow pin 2C. See how the Brown/Black wire is split off to four or five different sensors? See how each time it splits off the split off represents a mechanical splice in the Brown/Black wire. See how if a splice is irregular that the ground signal will be compromised? See Jane run. Run Jane run. (couldn't help myself {humor}). OH, and the 5v ref signal wire, the brown/white, has similar potential problems.
Brown/Black on a series four anyway. Some other color on late series four/series five.
Your main ground is that big *** wire on your outboard starter bolt. The same wire that is grounded to the chassis just under the left strut tower before it reaches the battery neg terminal.
