    Don't have an answer but my 99 s-10 has same symptoms and I've replaced the same plus plug wires and also got a PCM code p1621 for memory. Let me know if you find an answer, please

    Manifold absolute pressure sensor and throttle position sensor can also cause this code along with a failing fuel pressure regulator and leaking fuel injectors.
