Default low mpg

hey guys the last time i had posted anything on here it was low mpg and having trouble with my little 4cyl. it took me a while but i had found the problem with it. i had recently read a book on vacuum leaks and how they effect the fuel trim on the ecm. anyways i had found 2 very small vacuum leaks that made a 4 mile per gallon difference. i had fixed those and then put some prestone fuel system cleaner for carbon deposit. now im back up to 20 miles to a gallon. i hadnt seen that in like 3 years. now the only thing that is wrong with my truck are the back up lights. for the ax15 the switch is like 100 and something bucks. so it still will be a while before i will get that one. thanks guys for all your advice.

i dont know the truck is only rated for 20/25 mpg. it back to where it was when i first got the truck. im just glad to see 200 mile without filling up the truck for 40 bucks. 200 mile was 3/4 tank now its a little under 1/2 tank. it runs smoother and everything too.
