11. Remove the retainer nuts from the fuel rails. There are 4 retainer nuts, along with some bolts that hold the vacuum pipes in place. Remover all the nuts off the fuel rails for ease. There is also a bolt holding the MAP (Manifold Absolute Pressure) sensor on board. Take ‘er off and you’ll be a happy camper.
12. Disconnect the connector from the MAP sensor.
13. Now its time to remove the fuel rails. This will be both trying and fun. The right fuel rail comes off without a hitch, just apply evenly distributed pressure upward on the rail and it will pop right off. The left hand side can be a little trickier. The metal vacuum hoses have to be moved around quite a bit. Also, the large AC tube that I’m sure you’ve noticed by now and wondered, “When the f*** are we taking that thing outa here?”…..well we’re not. At least I’m not; you’ll just have to work around it. She stays for the whole ride. Work the vacuum hoses around, move the plastic wire harness out of your way and try to maneuver. Give it time.
Place the fuel rails upside down off to the side. I recommend not taking the injectors off the rails. There are 2 o-rings per injector that would need to be replaced and the injectors themselves cost about $100 a piece. So be very careful.
Part 2: The air intake
14. Next is to remove the entire air/throttle assembly. Star by unhooking the 4 clips that hold the air filter box. Remove the 2 pipes and the vacuum tube and loosen the clap screw. Remove the entire assembly and toss it aside. Also, there is a thick pipe which comes out of the air pipe and goes direct to the throttle body. Take out the support screw on the valve cover, disconnect the other end of the pipe on the throttle body and throw that pipe aside.
15. To remove the TCS Sensor/Actuator assembly, remove the 2 support brackets on the top and bottom of the assembly. Disconnect the connector on the top which is the valve sensor, and on the bottom which is the actuator itself. Loosen the clamp screw and take the assembly off.
