3.4L V6. Engine light came on, got codes to change coolant sensor and proximal O2 sensor. Changed both, engine light off now. Continues to run ruff, especially when it warms. Changed plugs and plug wires with no change. Tried Fuel additives and higher octane fuel for the heck of it. Possible coolant sensor still bad? Any ideas?
have the same problem?
