Greetings. Have read a lot but can't find my situation. 1993 Legend Sedan. Intermittent power assist at low speeds. Highway speeds drives like a beast. Fluids are fine, no check engine light, speedometer works as intended. Diconnected variable speed sensor located on engine by oil filter. D4 light flashed and no speedometer but no check engine light. Reconnected wiring and D4 went out and speedo retruned to normal. New refurbished rack 2 years ago, no leaks and fluid colour is normal. Would really like some opinions.
