  Q: How to service and repair the fuel injectors on Toyota MR2 Spyder?

  A: The first step for servicing fuel injectors requires removal of suspension upper brace and No.2 cylinder head cover and separation of the PCV hose and 3 wire harness clamps from clamp brackets. Unplug the 4 injector connectors and remove 2 bolts which secure the delivery pipe to the cylinder head to complete the disconnection of delivery pipe and 4 injectors without letting the injectors fall. The 4 injectors must be pulled from the delivery pipe after removing all 2 spacers and 4 grommets. Each injector should then have its matching O-ring disassembled for removal. Installation requires applying spindle oil or gasoline to each new O-ring before installing the ring to every injector followed by the procedure of setting both spacers and four new insulators on the cylinder head. Apply little spindle oil or gasoline on each O-ring contact point before feeding the delivery pipe injector while rotating it unto position. Place the 4 injectors into the delivery pipe contacts ensuring each injector faces up. Test the 4 injector movement after installing the delivery pipe to the cylinder head with temporary bolt attachment. If injection movement is restricted, replace the O-ring. Confirm all elements and after confirmation complete the delivery pipe cylinder head bolt installation to 19 N.m (190 kgf.cm, 13 ft.lbf) while attaching the 4 injector connectors. End the installation process by joining the 3 wire harness clamps to the clamp brackets then attaching the PCV hose and installing the No.2 cylinder head cover and suspension upper brace.
