Installed cobra intake...I think I am missing a sensor? help

thanx for looking

I installed a cobra intake and it's running pretty rough. already checked the time and a fireorder.

the only thing I can think of is a sensor plug ontop of the lower intake. it's missing it. Well, I am not sure if it's even a sensor that goes there? any info is appreicated.

Also, it's running really rich. is that cause I installed a phenomic spacer? thanx

also, i removed the smog pump and lines...does that have something to do with it?

Where’s the generally location on your lower manifold of the so called sensor your referring to, front right, front left or in the rear?

Due to running rich I will guess ACT or ECT.

Your first post is unclear though. Did the stock manifold have a sensor that you could not mount in the new manifold?
Did you find a plug that does not go to anything?

phenolic spacer shouldn't cause issues, nor should removing the smog pump stuff.
