Knock sensor (help)
My girls 2005 silverado 5.3 thru a rear knock sensor code, i thought maybe its because she put 87 on this fill up, normaly she puts 91 every time, so i put 91 in it, cleared the codes and drive it for a few miles and the same code poped up on the third ignition cycle. i just picked up two new knock sensors, the wire harness, and intake gaskets from the local chevy dealer $200 later, i planed on installing the new knock sensors/wire harness this week end but thought i should askes some of your opinions on if im on the right track with this? also how hard is this job? thanks David!

I think that you'll have it covered with all that, it's common for the knock sensors to corrode from water intrusion, there's a TSB in reference to this...if you search the GM section for "knock sensor", you should find pics that guys have posted of their knock sensors with a dam of RTV around where they go through the valley cover, as outlined in the TSB.
