Im fixing to start putting my top end back together and I was wondering if I didn't put my Evap Canister Soleniod Valve back on would it set codes off since it would be unplugged? The two vaccum lines that run to it are the canister and to the TB. So would it trip codes if I left it out. Also when I got a new computer burned I got them to disable EGR so that electrical hook up for it wont set codes either right? Heres a pic of the Canister Soleniod Valve.
