Still have my "miss" but I think it's something that needs to be tuned out.

Thank you again!

Oh and another word on the new injectors, the more i drive the jeep the better it gets! Its mostly a crawler, but it does see some street time, especially driving to the trails. I've put 200ish miles on them so far and performance both on the street and dirt is much improved. Starts are much smoother and faster, idle is still glass smooth, and throttle response is super crisp That miss is still there, and last time i pulled codes had a "loss of cam or crank" code so I'll be investigating that.

Thanks again!
