just swapped knock sensor question well lately I've felt a huge loss in power and have been throwing a code for a bad knock sensor (p0332) how long should it take after I swapped both knock sensors for my timing to correct itself? I thought it would be an instant change
you can do 1 of two things to get it back in spec quick. One is resetting the pcm by unhooking the battery. Then just prime the fuel pump a couple times and start it up. The pcm will have to relearn everything but the timing will be back in spec immediately. The other option is go to the gas station and put more than 1/2 tank in. When the pcm sees more than a 1/4 tank change in fuel level it will reset the timing tables.

I've seen it a number of places one was even a GM rep when he as commenting how on the new l99 camaros you have to reset the pcm to reset the timing takes while the ls1 fbodys did it when more than 5 gallons was put in. To the op I honestly dont know why it wouldnt have worked. If it makes you feel better just unhook the battery for about 30 min
