Down in the Techtips section of the board SL1CK has a tutorial on cleaning the TB... in the 5th picture the IAC Valve has a blue box drawn around it in the upper left hand corner.

I am not positive, but I don't think the '95 has an IAC valve. I think the '95 still used the ISC motor to control the idle. The IAC valve came in '96 I think.

ok thank you for the tip to look at slick posting...but thats not the way mine looks...i have a tube like tunnel thing going from my throttle body to my air intake i dont have the screws to take out the TB...for some reason there is like 2 vacume hoses on top of my TB going to something toward my firewall, my TB sensor is under the left side of the TB, Im all over the place I hope you can get an idea of what im talking about, if not I apologize...anyway thats not what my TB looks and i dont have all those sensors around it

code is sayin P027 (open throttle signal switch) maybe i do have a ISC motor instead, because im looking on pictures of internet northstar 95 motors and mine looks diffrent as i explained....uhhhggg im getting so frustrated

Sl1ck's picture are of a 96, Ranger is correct, your 95 has an ISC instead of the IAC. Take a look at the link below your ISC should be item #6.

Yup, the open throttle switch is on (or in) the ISC motor. It tells the ISC motor when the engine is at idle or at "open throttle".

yes!!! perfect, thank you...now with the bolt that goes in the middle of the ISC motor, do I have to adjust it to a specific postion or just put it in? Thank you 00 deville and you also Ranger great help...

With the engine at idle, press on the plunger. It should retract. When it bottoms out, unplug it. Set the gap to .030 and plug it back in.

This is a 1996 it should be similar if not the same. It's very easily removed to wash out the chamber in there & wipe the carbon off the pintle.
