cant find these things
 
Hey guys , need help finding a couple of things.

My car has a bit of a rough idle and i am trying to figure out how to unplug my Air flow sensor. Ive looked at several sites/haynes book and it says there is a plug on the side that just doesnt exist on my sensor.

Also where/what the heck is the Vaccum delay valve?I just bought the car a couple of months ago and 1 of the service records says this is sticking. here is a photo of my engine bay.

here is my Air flow sensor.http://s596.photobucket.com/albums/t...nt=AirFlow.jpg

Any help would be appreciated. Also this morning i upped the idle just a tad and that helped a little bit but the idle is still rough. I have cleaned the idle air motor/ throttle body . I dont think i have any vacuum leaks and i have recently replaced the plugs, wires, cap, rotor, o2 sensor, air filter and Ignition coil.

thanks again, matt

Your K-jet car doesn't have a air mass meter that you can unplug like on a LH car. It has a mechanical air flow plate.

Alright good to know,

How about the vacuum delay valve? I know i have one of those or it wouldnt be on the service record from 3k miles ago. Im just trying to find it so i can replace it.

Kinda sounds like what hangs off the control pressure regulator

Hey just wanted to say that i really appreciate your help. You help alot of people on here and we all very much appreciate it.

Ill check out the delay valve and see if that helps.

Is the control pressure regulator the same as fuel pressure regulator?
