I was told that sometimes in cars if it misses to check the plug leads with a multimeter. As its often overlooked with carbon leads. supposed to be around 11-12 ohms but mine are around 7 ohms. Is this a factor in performance? Should i replace them? I've had my 1990 maxima for about 5 years now (2nd hand) & had never changed the leads.
Anyones views on this?
