Smgreen1025 Posted December 7, 2022 Share Posted December 7, 2022 (edited) Changed plugs, about a week later it started stalling out and running rough. Tried everything I can think of. HELLP!!!! I recently switched to full synthetic oil, tried changing wires, throttle position sensor and switched from the Bosch double platinum back to regular Champion plugs. Tried resetting the PCM to no avail. Could it have jumped timing? Is it possible that the synthetic oil broke some sludge free? Im out of ideas...
