I realise you mentioned that you have no vacuum leaks , but have you checked the intak manifold gaskets for vacuum leak?
if so check your distributor cap for any sign of cracks
also have you had or checked your timing?
check your fuel vapor canniste to ensure it is working properly
Are the spark plugs gapped properly?
also check to se if your rotor in the distributor is good or not
