Replace fuel injecters 1987 trans am?

Answer 1

This is assuming you have a TPI engine, and an above average tool set, and good mechanical ability. First you need to disconnect the intake duct from the throttle body, then take the four 10mm bolts out of the throttle body. Next take the bolts out of each side of the intake plenum, unplug the MAT sensor from underneith the plenum, and the vacuum lines. Then remove the plenum, then take the 4 10mm bolts out of the fuel rail. You now have to unlock the factory clips at the top of the injectors, do this by rotating them clockwise until the hook is positioned to the left of the injector. Bleed off the fuel pressure by using the shrader valve on the fuel rail. Carefully using a prybar, lift the fuel rail one corner at a time, using WD-40 to lube the injector o-rings at the intake. Once the rail is lifted to obtain clearance to remove injectors, pry injectors out of the fuel rail, one at a time, don't try to take them all out before replacing. One at a time lube both o-rings on the new injector, and install into rail, repeat this until all are done. Then reinstall the rail and injector onto the intake manifold. This is not an easy task, requires a little patience and finess. Good Luck
