Some of the most neglected items on my car definitely had to have been the fuel filters. I slapped some new ones in this afternoon and was amazed at how much the change effected the engine's performance. The car ran well before, yet it now idles smoother, revs more freely, and has more seat of the pants feel of power (wishful thinking). Upon inspection of the clear plastic filter, I noticed sort of a brownish yellow hue, could that have been algae?
Another benefit was spraying the engine with Engine Brite and hosing it down. Some how this must have cleaned the tach sensor and I now have a fully functional tach!

Tomorrow: my first valve adjustment! (thanks Thomaspin for your excellent website!)
