Incredible 1996 4Runner Clearing Check Engine Light 2023. (unless it's a hard code) __________________. I have found the seatbelt, abs, oil lamp, battery, airbag, low fuel, at/p, 4x4 symbol, ect, rr diff lock lamp, bright light lamp, etc but nothing even resembling a engine or check engine warning light.
If plugs are old, i'd start with new plugs, and look carefully at the ones you pull out. A wet or fouled one, or one different from the others, is always a clue. Web any vehicle made for the 1996 model year and up uses the same protocol.
