What condition are your plug leads? Age plus the heat coming up from the exhaust manifold can cause them to deteriorate.i had a misfire/ rev problem on an Escort and new leads solved it. Mine was an efi cvh engine. I bought standard new leads and not expensive up market ones.
Remember to change leads one at a time to make sure they are in the correct firing order!
