Hi all.

I recently just finished my single install, Seems to be running good, but the other day I started it up and my CEL light came on. So I checked both codes, 12 and 52

I looked at what both codes are. Knock and CPS, I checked all my plugs and connections etc etc. my knock sensors are done with sheilded wire and so on. Everything looked in order.

But the car seems to rev kinda sluggish, and I was inspecting my intake manifold plugs closer and.. well I can't seem to find my 3rd Intake mani ground :ugh2:

My question, Does one of the grounds on the intake manifold tie into the Cam and knock sensors ?
Any input is appreciated
