You have an air vacuum type leak around the intake manifold area , computer will continue to compensate the 14 parts air to 1 part fuel each time which makes it chase the problem back and forth.
You can try WD40 spray that can help find the leak and not hurt the distributor or elec. Tighten up all bolts you can find on top of motor , to see if any loose. If you find leak just use some silicon. Could also just be a small vacuum hose came off somewhere.
