Need Help: Where Does This Go?

[Luang]

I just finished putting my parents van back together after doing the intake manifold gasket and have 1 wire harness that is not plugged in and have no idea where it suppose to go so I need some help. Thanks in advance for the help

It's a 2001 Pontiac Montana

Hard to see but looks like an O2 sensor plug.

Are you 100% certain you kept the pushrods in the right order? That sounds a little extreme to say let it run a while to let lifters pump up.

Ya bagged and tagged them all. How long should I keep it on before I know I fucked something up

Thanks i did it and it worked

Last problem is that now the idle while in park is around 2300 rpm and in drive around 1200. Any ideas?

Check for a vacuum leak. I tend to forget the brake booster hose on those stupid vans since the bay is so squished and it's clear in the back, then wonder what in the world is up with the idle...

sprayed some carb cleaner and couldn't hear a difference so i don't believe i have a vacuum leak

Maybe check your throttle cable then. It could be hung up on something, or check the cruise module and linkage hookups on the TB itself for binding and possibly causing the TB plate to be stuck partially open.

Checked and both cables are loose

Disconnect the TPS and see if the idle is fixed. Or if you have something that can show you the throttle percent, i.e. a scanner of some sort, check to see what it is. Should be zero at idle.

Disconnecting the TPS will throw a code for low TPS voltage, but the computer will report the throttle position at zero.

Idle relearn?

Idle relearn?

how do i do that

Idle relearn?

Not required on newer PCMs (ie, 3x00s).
