The fuel psi is good and the wideband stays around 14. As far as a dark test for underhood lightning, there is none. I have made no new mods since it started this. Can a bad set, or just one, knock sensor cause this? I have no codes coming up.

But you did highjack, and its not a good idea. Better to start your own thread.

If you have constant knock retard, up to 15-degrees, you probably have a fault in the knock sensor circuit.... but its better to start your own thread and not add any confusion to the original poster's thread.
