Out of the blue I started getting random kr during hwy driving and now at wot, not sure what to do. My tuner has pulled 4 deg vs where it was happy less than a month ago. I have a rotofab dry filter, ported tb and intake and have installed a wb. I have checked around for rattles from above. Its hard to listen for any ticks with the injectors and pump clacking away. This weekend Ill try to pull it on ramps and look under it. Seems to not have it or as much when the engine is cold and seems to increase as the engine warms up. Looking for suggestions and ideas please
