It was a 30AMP fuse for the engine controller. Was that what you meant BigJim when you mentioned the sparkbox?

I had the 4.2L that was in my Wrangler originally all figured out so now I get to figure out all the little problems with the 4.0L, still no regrets with the 4.0. I have gained 7 miles per gallon and about 70HP with swapping the two engines.

Thanks for all the help.
