Hi all,
I'm planning on changing the spark plugs on my HR in next few weeks but I'm very apprehensive about doing it given the issues that can happen if the throttle body butterfly valves are inadvertently moved - and thus causing a high / hunting idle.
It looks like for the spark plug change the throttle bodies need to be removed to access 2 of the 3 spark plugs on each bank.
Can someone confirm what I should be disconnecting - the battery and the ECU? any particular order? Any tips welcome. I've done the spark plugs on my old DE without issue but didn't need to remove the throttle body itself - just the intake piping.
Thanks
