I do plan on changing that hose anyway, just wondering if there's anything else I should look at before I order just that one part. Especially since I doubt the hose has gotten any worse since I last looked at it a few months ago and this problem has just recently appeared. Besides that, I'm trying to cut down on just throwing parts at this car, regardless of their cost.
