(10) Inspect fuel line quick-connect fitting-to-fuel rail
connection. On the 8.0L V-10 engine, the fuel line-to-
fuel rail connection is made at the rear of the engine.
(11) Verify that hose connections to all ports of vac­
uum fittings on intake manifold are tight and not leak­
ing.
(12) Inspect accelerator cable, transmission throt­
tle cable (if equipped) and cruise control cable con­
nections (if equipped). Check their connections to the
throttle arm of throttle body for any binding or re­
strictions.
(13) If equipped with vacuum brake booster, verify
that vacuum booster hose is firmly connected to fit­
ting on intake manifold. Also check connection to
brake vacuum booster.
(14) Inspect the air cleaner inlet and air cleaner el­
ement for dirt or restrictions.
(15) Inspect radiator grille area, radiator fins and
air conditioning condenser for restrictions.
(16) Verify that the intake manifold air tempera­
ture sensor wire connector is firmly connected to har­
ness connector (Figs. 8, 9 or 10).

(17) Verify that MAP sensor electrical connector is
firmly connected to MAP sensor (Figs. 11 or 12). On

(18) Verify that fuel injector wire harness connec­
tors are firmly connected to injectors in the correct
order. Each harness connector is numerically tagged
with the injector number (INJ 1, INJ 2 etc.) of its
corresponding fuel injector and cylinder number.
(19) Verify harness connectors are firmly connected
to idle air control (IAC) motor, throttle position sen­
sor (TPS) and manifold absolute pressure (MAP) sen­
sor (Fig. 11).
