Knock Knock...
I replaced both knock sensors on my 99, 4 Runner, 3.4, that has 353,550 miles. The sensors worked like a charm! Since I was there, I replaced the wiring harness also. After initial start up there was some knocking as the ECM needed to go through re-learning process. I highly recommend the product!
