[HondaCivicEx98]

Sorry for a dump question.
But what and where is the pressure swicth.
I am asking becasue i want to do Rafe TPS trick but it seems no one knows what i am talking when i go to perfornmace shop.

And, How do i get my high idle when the engine is cold back without taking out the JR relay? I need high idle in cold start casue my car shuts down, i guess is becasue is too cold.
thanks

The pressure switch is a bell shaped gizmo screwed into the intake manifold with a wire coming off it.

I've heard that the SOHC kits...at least the early ones did not have a pressure switch. So that could be part of the problem. It should be on the back of the manifold. It has a 1/4 inch threaded end and is black on the back. it should have one wire coming off of it.
