MINIMUM IDLE SPEED
The minimum idle speed should onl
y be adjusted under two conditions:
If the throttle body has been replaced.
After every other possible cause for the in correct idle speed has been explored.
There are many possible causes for incorre ct idle speed, most of which require
a high level of diagnostic skill as well as expensive testing equipment. Check
the vehicle for vacuum leaks, incorrect valve or ignition timing, deposit
accumulation in the throttle bore or valve, sticking throttle linkage or bent throttle
valves. If the vehicle will still not idle pr operly after checking these areas, it
should be diagnosed by a professional.
1. Pierce the idle stop screw with an awl. Apply leverage to remove it.
2. Make sure the IAC valve is connect ed. Short the A and B terminals of the
ALDL connector together with a length of wire.
3. Turn the ignition to the ON positi on, but do not start the engine. Wait at
least 30 seconds before proceeding.
4. With the ignition ON, disconnect the IAC valve connector.
5. Separate the set-timing connector. Th is eliminates the possibility of
changes in engine speed due to variations of engine timing.
6. Start the engine and remove t he wire shorting the A and B terminals
together. It may be necessary to hold the throttle open slightly to prevent
the engine from stalling.
7. Allow the engine to reach no rmal operating temperature.
8. Adjust the idle speed to the following: a. 2.8L Engines - 450-550 rp m A/T or 550-650 rpm M/T
b. 3.1L Engines - Refer to the underhood emissions sticker
c. 5.0L and 5.7L TPI engines - 400-450 rpm.
If these figures differ from t hose on the underhood emissions
sticker, always follow the specifications on the emissions sticker.
9. Turn the ignition OFF and connect the IAC valve harness. On models up
to 1989, adjust the Throttle Position Sensor.
THROTTLE POSITION SENSOR (TPS) 1. Install three jumper wires betw een the TPS and the harness connector.
2. Use a digital voltmeter connected to terminals A and B of the TPS.
3. Turn the ignition switch ON , but do not start the engine.
4. Loosen the TPS attaching screws and adj ust the sensor to the following:
a. 2.8L Engines - 0.50-0.60 volts
b. 5.0L and 5.7L TPI Engines - 0.47-0.61 volts
5. Tighten the attaching screws, then check that the reading has not been
disturbed.
6. With the ignition OFF, remove the jumper wires. Reconnect the TPS
harness.

5.0L AND 5.7L TPI ENGINES
1. Disconnect the negative battery cable.
2. Relieve the fuel system pressure.
3. Remove the intake plenum and runners.
4. Remove the fuel rail assembly.
5. Rotate the injector retaining clip to the unlocked position and remove the
injector. Discard the O-rings and the injector retaining clip.
There are two different injector part numbers for the 5.0L and the 5.7L engine.
Do not intermix injectors with different part numbers, as this will result in engine
roughness and excessive emissions. When or dering new injectors, be sure to
order the identical part number that is inscribed on the old injector. However, if a
complete set of injectors is being repl aced, either part number for that engine
application may be used.
To install:
6. Lubricate the new O-ri ng seals with engine oil and install them on the
injector. Assemble a new reta ining clip on the injector.

GENERAL INFORMATION & MAINTENANCE

HOW TO USE THIS INFORMATION
The introductory part of this repair gui de is intended to help you learn more
about the inner workings of your Camaro while saving you money on its upkeep
and operation.
The beginning of the repair guide will likely be referred to the most, since that is
where you will find information for maintenance and tune-up. The other
information deals with the more complex systems of your vehicle. Systems
(from engine through brakes) are covered to the extent that the average do-it-
yourselfer can attempt. This repair guide will not explain such things as
rebuilding a differential because the ex pertise required and the special tools
necessary make this uneconomical. It will, however, give you detailed
instructions to help you change your own brake pads and shoes, replace spark
plugs, and perform many more jobs that can save you money and help avoid
expensive problems.
A secondary purpose of this repair guide is a reference for owners who want to
understand their vehicle and/or their mechanics better.
WHERE TO BEGIN
Before removing any bolts, read through t he entire procedure. This will give you
the overall view of what tools and supplies will be required. So read ahead and
plan ahead. Each operation should be approached logically and all procedures
thoroughly understood before attempting any work.
If repair of a component is not considered practical, we tell you how to remove
the part and then how to insta ll the new or rebuilt replacement. In this way, you
at least save labor costs.
AVOIDING TROUBLE
Many procedures in this repair guide r equire you to "label and disconnect ..." a
group of lines, hoses or wires. Don't be think you can remember where
everything goes - you won't. If you hook up va cuum or fuel lines incorrectly, the
vehicle may run poorly, if at all. If you hook up electrical wiring incorrectly, you
may instantly learn a very expensive lesson.
You don't need to know the proper name for each hose or line. A piece of
masking tape on the hose and a piece on its fitting will allow you to assign your
own label. As long as you remember your own code, the lines can be
reconnected by matching your tags. Re member that tape will dissolve in
gasoline or solvents; if a part is to be washed or cleaned, use another method
of identification. A permanent felt-tipped marker or a metal scribe can be very
handy for marking metal parts. Remove any tape or paper labels after
assembly.

Loctite). If you're worried about getting so
mething together tight enough to hold,
but loose enough to avoid mechanical damage during assembly, one of these
products might offer substantial insurance. Before choosing a threadlocking
compound, read the label on the pa ckage and make sure the product is
compatible with the materials, fluids, etc. involved.
3. Crossthreading. This occu rs when a part such as a bolt is screwed into a
nut or casting at the wrong angle and forced. Cr ossthreading is more
likely to occur if access is diffic ult. It helps to clean and lubricate
fasteners, then to start threading the bolt, spark pl ug, etc. with your
fingers. If you encounter resistance, unscrew the part and start over
again at a different angle until it can be inserted and turned several t\
imes
without much effort. Keep in mind t hat many parts have tapered threads,
so that gentle turning will automatica lly bring the part you're threading to
the proper angle. Don't put a wrench on the part until it's been tightened
a couple of turns by hand. If you s uddenly encounter resistance, and the
part has not seated fully, don't force it. Pull it back out to make sure it's
clean and threading properly.
Be sure to take your time and be pati ent, and always plan ahead. Allow yourself
ample time to perform r epairs and maintenance.
TOOLS AND EQUIPMENT
Without the proper tools and equipment it is impossible to properly service your
vehicle. It would be virtually impossible to catalog every tool that you would
need to perform all of the oper ations in this repair guide. It would be unwise for
the amateur to rush out and buy an expens ive set of tools on the theory that
he/she may need one or more of them at some time.
The best approach is to proceed slowly, gathering a good quality set of those
tools that are used most frequently. Don't be misled by the low cost of bargain
tools. It is far better to spend a little more for better quality. Forged wrenches, 6
or 12-point sockets and fine tooth ratc hets are by far preferable to their less
expensive counterparts. As any good me chanic can tell you, there are few
worse experiences than trying to work on a vehicle with bad tools. Your
monetary savings will be far outweighed by frustration and mangled knuckles.
Begin accumulating those tools that are used most frequently: those associated
with routine maintenance and tune-up. In addition to the normal assortment of
screwdrivers and pliers, you should have the following tools:
• Wrenches/sockets and combination o pen end/box end wrenches in sizes 1/83/4 in. and/or 3mm-19mm 13/16 in. or 5/8 in. spark plug socket
(depending on plug type).
If possible, buy various length socket drive extensions. Universal-joint\
and
wobble extensions can be extremely usef ul, but be careful when using them, as
they can change the amount of torque applied to the socket.
