Its funny you posted that question. I was going to get on and ask how many i needed to use.. But as far as installation

On the top of your throttle body there is a sensor that is screwed in with TWO screws. Take the screws out and pull the sensor off. On the bottom where the sensor used to be you will see a whole in the intake mannifold. What you do is you take the check valves how ever many you uses and "tee" them in to a vacume hose for example

(hole in TB)-----C-----C----C----(map sensor)

C's being check valves
--- being vacume hose

The map sensor is easy to find its at the top of the throttle body bolted right in to the thottle body!
hope that helped

use three.

t them to the line going to the map sensor.

the idea is to bleed all the boost away from the map sensor. the check valves wont allow boost to get to your map sensor, therefor it never sees boost. very easy concept.

That is all true. but keep in mind 88-91 civic/crx had the map sensor on the firewall and there is a vaccum hose going from the throtle body to the map sensor. Yo replace that line. On 92+ civics the map sensor screw right on top of the throtle body. In which case you unscrew it and do what they said before.

Always use check valves, if your not using a piggy back fuel controller, like an AFC. Not only when you get the CEL
