Greetings,
I have a 1996 Tacoma 4X4 with automatic transmission and almost 100K miles. I was getting about 20 mpg, but about 3 months ago it suddenly dropped down to about 17 mpg. It happened from one tank to the next (and has been consistent since) with no change in performance. I took it to my mechanic who said it's running fine (neither rich nor lean) and said it wouldn't be worth hooking up a computer since I don't have the "check engine light". According to him, the only inputs to the computer are the same as the inputs to the check engine light. Any ideas??
