Is there any way to test the coils to see if they are bad? I have what feels like a miss above 3000 rpm and the truck surges. If so do you need special tools??

Thanks

A scope and an inductive low amp probe. That and/or a secondary inductive pickup. You'll need to know what you're looking at though.
