Can a bad alternator affect fuel \"economy\"?
The alternator on my 88 302 just went. Previously, I was getting bad fuel "economy" - about 10.5 mpg. After changing the alternator, the mileage seems to have improved a little, though I haven't taken the time to actually figure it out.
The alternator holds the charge, which in some way has to manifest itself to the sparkplug. If the spark isn't there, then wouldn't it stand to reason you're not getting all the bang you could in the chamber and are just wasting gas?
Enlighten me, please.
