Those don't have points. I have one and it has a Hitachi disty. Maybe it's the Ignition Control Module in the distributor getting hot and breaking down. Standard Part # LX515
I think it's with the introduction of CANBUS which is like 2005 in the US market. So it would be 2004 and earlier are no big deal to swap diff ratios. After that I'm unsure what happens, but that's when the potential to run into more issues starts to present.
