i would think the mixtures are too rich.. this can happen under the radar of the ecu!! i suspect youy may have a faulty mass air flow sensor or lambda sensor or both... first of all, check there are no air leaks on the inlet manifold and associated hoses. this will alter the mixtures aswell. check everything you can see physically before going for the engine management.. hope this helps!!
