Hi there
A few weeks ago we picked up an e34 M50 engined 520i for a banger rally we are doing to Prague called Czechwrecks
Well the car is great - a bargain for less that £100! It just has one little fault, a slight misfire under load.
Well I've bought new plugs, 6 2nd hand Bremi coils and a valve cover gasket as there is a little oil in the plugs that I will be fitting in the next couple of days. But upon inspecting the engine I noticed that 4 of the 6 coils are earthed and 1 & 2 aren't.
#6 earth strap
#5 bracket connecting to #6 and #4
#4 bracket connecting to #5 and #3
#3 earth strap
#2 nothing
#1 nothing
the last 4 coils are the original coils (the ones that fail, I can't remember their name) and 1 & 2 are Bremi coils, both with different part numbers. So have obviously been changed at some point in the past.
So my question is, do coils 1 & 2 have to be earthed?
A very long winded post, but i thought I'd give you as much info as possible.
Thanx in advance
