Ok so i changed my oil last week from winter weight 5w-30 royal purple to summer weight 10w-30 valvalin synthetic. i changed the filter oil and re-did the seal on the valve cover. nothing new except oil. so my problem is now my jeep wont idle and it is putting out black smoke like its its job. if i rev the rpms up while in gear 1 and 2 when i hit 3400 it starts to cut out. so i really dont know whats wrong but its making me mad. So should i just change the oil? or did something else go wrong at the time of the oil change?
