Okay so here is my problem, I just finished rebuilding my 3.0L V6 in my 4 runner. It has been bored out .50 and now my Knock Sensor is going crazy. Everytime I drive it just around the corner the light comes on the book I have says it has an open circuit. The only problem is the book is a haynes. I have taken 2 yrs of college to work on cars but this is boggling my mind. I have checked my spark plugs, timing, and fixed my one exguast leak. If you have any ideas please let me know.
