Hi guys. As per the title this has been an issue on and off for a while. symptoms are classic coil issue so I just want to clear a few queries before I attempt to get it sorted.
Should I expect to have to replace all 4 or can I find which one is the problem and just replace that?
Should I replace spark plugs at the same time?
Can I establish which is the culprit without a scanner? (Visually)
Is it wise to buy a used replacement?
Hopefully these aren't ALL stupid questions!
In the UK if that makes a difference
Cheers!
