old post but see it asked many times.
assemble the rail first, its 1 piece so must be ready first.
3.7L Engine (FSM) RTM?
(1) If fuel injectors are to be installed, refer to Fuel
Injector Removal/Installation.
(2) Clean out fuel injector machined bores in
intake manifold.
(3) Apply a small amount of engine oil to each fuel
injector o-ring. This will help in fuel rail installation.
(4) Position fuel rail/fuel injector assembly to
machined injector openings in cylinder head.
(5) Guide each injector into cylinder head. Be careful
not to tear injector o-rings.
(6) Push right side of fuel rail down until fuel
injectors have bottomed on cylinder head shoulder.
Push left fuel rail down until injectors have bottomed
on cylinder head shoulder.
(7) Install 4 fuel rail mounting bolts and tighten.
Refer to torque specifications.
(8) Install 6 ignition coils. Refer to Ignition Coil
Removal/Installation.
(9) Connect electrical connectors to throttle body.
(10) Connect electrical connectors at all fuel injectors.
To install connector, refer to (Fig. 37). Push connector
onto injector (1) and then push and lock red
colored slider (2). Verify connector is locked to injector
by lightly tugging on connector.
(11) Connect necessary vacuum lines to throttle
body.
(12) Connect fuel line latch clip and fuel line to
fuel rail. Refer to Quick-Connect Fittings.
(13) Install air box to throttle body.
(14) Install air duct to air box.
(15) Connect battery cable to battery.
(16) Start engine and check for leaks.
Cleaning the throttle body often fixes this problem otherwise you will likely need to replace the throttle control motor. At the throttle control motor monitor the clutch operation. Check to see if the computer is supplying the clutch circuit with a 12 volt square wave pulse signal. With the key in the on position, check to see if the throttle motor makes a buzzing noise as the throttle is opened and closed. With the key off, push the throttle plate open with your finger and allow it to close. The throttle plate should open and close smoothly.
The 1984 model could be throttle body injected or a regular 4 barrel carb. The GT model is supposed to have a carb. CFI is central fuel injection which is like TBI. The throttle body has two injectors mounted in the center, one for each bank. If it has a carb you may have some adjustments you can make. If it is fuel injected you don't. The computer monitors the engine temp and exhaust gas to regulate fuel mixture.
There are two kinds of injection... throttle body looks like a carburator, and has one or two injectors in it,
Multiport has an injector for each cylinder. A multiport wont have a throttlebody, but both do have other parts, like an idle air control valve, and other items that could be cleaned.
I would recommend adding injector cleaner to the fuel, and spray some carburator cleaner into the intake while running. Just an idea!
I'd guess with a 1989 you have throttle body fuel injection, which means that the "injector" is in the metal part that would be where the carburator used to be. Old cars had the air filter on top of the carburator.
you really can't see much of it.
