can someone do me a favor and take a picture of how the vacuum lines on the intake manifold is plugged. my motor is a h23a1 and the vacuum hoses came loose and i dont know how or where it is suppose to be connected correctly. the way that i have the vacuum lines plugged in now works but it chokes and lag in low RPM ranges in all gears. any other way i tried, makes the car's RPM jump up and down twice before turning off. before the vacuum lines were misplaced, my car was driving fine.



the red line goes from the far left on the back of the manifold to the top part on the side. the yellow one goes from the right side of the back of manifold to the sensor on the wall. the green goes from the bottom of the side to the sensor on the side of the car. the blue one goes no where. if you can, please let me know how these four vacuum hoses go on your h23a1 motor. thanks

i've already tried that. it still didnt work correctly. going along with that diagram, the RPM shoots up and down twice and then the engine turns off.

You can cap off the cruise control actuator vacuume port on the manifold if you are not using the cruise control.
