LS1 DS head grounds
Hey all,
I am trying to diagnose what appears to be an electrical/sensor issue. I read somewhere that putting all 3 grounds in one spot on the back of the driver head can lead to issues. I was lazy and did this. Does anyone know which two wires should ground together and what one is solo?
Thanks in advance

I think you just need to make sure the 3 big lumps of the motor are positively grounded to each other,, Both heads and the block. Bad grounds are the playground of the devil LOL

I have replaced the intake seals and correct torque/pattern was used. No change. This comes and goes as it pleases. Most of the day the car runs great, but then it just runs poor, like a misfire, and one or both knock sensor codes will set off the SES. I can clear the codes, let the car sit, and maybe it will run fine next time it starts. The problem will sometimes stop just as quick and the SES will turn off.
