Lol, that thread continued on for a bit. I thought all LS1's had a somewhat noisy valve train. If I heard wrong, by all means correct me.

So I was thinking the right side cat plugged but it appears to be working on the scan tool and with a temp reader gun. Its missing so bad it sounds like its knocking, any ideas??? The vehicle is a 2002 1500 with a 5.3.

I'm having a problem with #7 and #8 misfire. I came across some information regarding your problem. Follow the ground for that wiring. It goes to the block.. if it doesn't look too good take it of and clean the ground
