Check your air filter, make sure it is clean. Try some Seafoam injection cleaner or a Good quality Injector cleaner. Also check the timing, there is a brown single wire close by the distributor that you have to disconnect. Then check the timing and then reconnect it. It will throw a trouble code, but that will clear.
