Soot on drivers side spark plugs. 3.2L V6 It has a slight missfire after it warms up. Has electronic egr valve and don't see anyway to look for valve moving. Cleaned valve and reinstalled. Ceaned o2 sensors still same problem. Also blows dark smoke when you revup the engine going down the road. Sometimes it white smoke when it's first started up. Tail pipe is blak and sooty. Not loosing any oil or coolant. How do I check th O2 sensors and know there location. How do I check this type of egr valve? EGR VALVE -- Pin type; With 5-prong male terminal and 2 mounting holes. Could it be the timing belt?
