Hello,
If you are sure no vacuum leaks a few off ball/exotic issue I might check. First make sure the elbow at the charcoal cannister is not your leak.
Check timing. I have seen a damaged reluctor wheel and or failing crank sensor make timing on a NA car move something like 120 degrees. I have only seen this 2 times but I tried many things before I came across it.
Another potential issue could be a clogged cat or muffler. If you loosen the nuts holding the head pipe to the manifold a few turns you will create a large exhaust leak. But if the car runs good you will know you issue is in the exhaust somewhere. Do not run it long like this. Good Luck, Bernie
