The most common thing I've seen causing this code is a worn distributor gear. Remove the distributor to check if the gear is worn allowing play, if so then it needs to be replaced. The next most common thing to cause it is injectors, I would get some injector cleaner to run through engine too. Let me know how it goes or if you have more questions, thanks Larry.
