Just replaced the knock sensor, short loom between sensor and main loom on a 91 V6 4x4 Pickup. The job required removing the timing belt to be able to remove the intake manifold. So, because of wear on the belt , tensioner pulley, and large upper idler pulley replaced them also. My customer thinks I charged him too much labor. Wondering how many hours you Toyota Line Techs bill for a job like this. Alldata Flat Rate doesn't seem to even be close to real time.
