Disconnect fuel tube quick connector at vehicle piping side.
To remove the quick connector cap, hold the sides of the connector, push in the tabs and pull out the tube.
CAUTION:
The tube can be removed when the tabs are completely depressed. Do not twist it more than necessary.
Do not use any tools to remove the quick connector.
Keep the resin tube away from heat. Be especially careful when welding near the tube.
Prevent acid liquids such as battery electrolyte, etc. from getting on the resin tube.
Do not bend or twist the tube during removal or installation.
Do not remove the remaining retainer on the tube
When the tube is replaced, also replace the retainer with a new one.
To keep the connecting portion clean and to avoid damage and foreign materials entering, cover the ends of the fuel tubes with plastic bags or something similar.
NOTE:
If the connector and the tube are stuck together, push and pull several times until they start to move. Then disconnect them by pulling.
Remove the fuel rail with the fuel injectors attached, from the intake manifold. Remove the fuel injector O-rings and use new O-rings for installation.
Loosen the bolts in the order as shown, and remove the intake manifold with power tool.
Inspection AFTER REMOVAL Surface Distortion
Using straightedge and feeler gauge, inspect the surface distortion of the intake manifold. Inspect the surface distortion of the intake manifold collector. Refer to See: Intake Manifold Collector.
Standard : 0.1 mm (0.004 in)
INSTALLATION
Installation is in the reverse order of removal. Follow the procedure below for specific tightening sequences and procedures.
Install intake manifold bolts in two steps in the numerical order as shown.
NOTE:
After installation, it is necessary to re-calibrate the electric throttle control actuator as follows:
