Have done a bit of searching as my car has a slight idle problem (drops slightly every 10 seconds or so)
I have noticed my temp gauge in the car seems to fluctuate quite a bit ie.. 1 min its about 80 then its right down then it shoots up to normal running temperature.
I changed the plugs from BRK5's to ngk BRK6's and it hasn't made a difference so im wondering if it could be down to the earthing problem.
i have a new coolant sensor to put in and i will do the earth tomorrow? does anyone have any idea what the gauge of wire does the earth connection?
Cheers in advance and ill let you know if problem is solved
