I was wondering if there was any way to prevent the opti from failing like it did on me last week. I don't want to have to go thorugh the process very often. thanks

 

make sure the water pump isnt leaking is about the only thing i know for sure. i havent ever heard of to many things that can prevent it from failing. Its a POS that is why it fails.

 

the opti spark isnt that bad of a thing. ive had three lt1 cars including two impy ss and 1 camaro and none had any trouble before 100,000 miles. besides they arent that bad to change either all you need is a little time to get some stuff out of the way. Routing the new plug wires also becomes much easier if you take the AIR system out.
