4. Attach the red clip of the attachment to the battery as follows:
+ terminal - 1983-1985 RX-7
- terminal - 1981-1982 RX-7
5. Start the engine. Raise the engine speed to 3000 rpm and release
the throttle. Check that the green and red lamps illuminate at
the same time.
6. If the green and red lamp do not illuminate at the same time,
proceed as follows:
* Remove the cap from the adjusting screw. See Fig. 6.
* If the red lamp illuminates first. turn the adjusting screw
counterclockwise until both lamps illuminate at the same
time.
* If the green lamp illuminates first turn the adjusting screw
clockwise until both lamps illuminate at the same time.
7. Install the cap on the adjusting screw.
8. Connect the connecter (brown) disconnected in Step 2.

TECHNICAL SERVICE BULLETIN

CALIFORNIA REFORMULATED GASOLINE

Model(s): All Mazda Models
Category: F - Fuel & Emission Control Systems
Bulletin No.: 014/96
Date: June 6, 1996

DESCRIPTION

This bulletin is issued to provide service personnel with
information to answer commonly asked questions regarding California
Reformulated Gasoline (CaRFG). Please use this information to address
customer concerns.

BACKGROUND

  * The purpose of CaRFG is to reduce emissions.
  * CaRFG replaces the traditionally high pollution generating
gasoline distributed in Northern California.
  * CaRFG improves the reformulated gasoline distributed in Southern
California.

The California Air Resources Board (CARB) expects smog forming
emissions from motor vehicles to decrease by approximately 15% due to
CaRFG.

MAZDA'S POSITION ON CaRFG

  * CaRFG does not affect the new vehicle or emission warranty.
  * Mazda recommends the use of CaRFG as a cost effective means of
reducing emissions to provide cleaner air.
  * Vehicle and laboratory testing of CaRFG ensures that CaRFG is
acceptable for customer use.
  * Based on the above studies, no unusual vehicle performance
concerns are expected.

DIFFERENCE BETWEEN CaRFG AND OTHER GASOLINES

CaRFG consists of the same basic components as other gasoline but,
pollutes less due to cleaner burning components and fewer toxic
components. These components provide:

  * Reduced aromatic hydrocarbons to form less smog emissions.
  * Added oxygenates to reduce emissions.
  * Decreases the amount of vehicle fuel evaporation.
  * Lower sulfur to provide more efficient catalytic converter

operation.
* Reduced benzene by approximately 50%.

CaRFG AFFECT ON VEHICLE PERFORMANCE

Properly blended CaRFG should have no adverse affect on vehicle
performance, engine durability or fuel system components. Basic
components of CaRFG are not significantly different from other cleaner
burning gasoline used in the United States for several years.

If the vehicle is a California calibrated 1996 or later model, the
vehicle will:

* Operate satisfactorily on gasoline in the other 49 states but the
emission control system performance may be effected.
* Using gasoline other then CaRFG may cause the Malfunction
Indicator Light (MIL) to illuminate or cause the vehicle to fail
an emission test.

CaRFG AFFECT ON FUEL ECONOMY

A very small reduction in MPG (less than one-half MPG) is possible
if the customer uses gasoline without oxygenates. This is attributed
to the lower energy content of oxygenates, which have been included in
all Southern California gasoline since January 1995 and some gasoline
since the 1970s.

NOTE: Driving habits, vehicle maintenance and weather conditions all
affect fuel economy. Fuel economy may vary more than 1 MPG from
one fill up to the next using the same gasoline.

NO SPECIAL ADDITIVES ARE NECESSARY WHEN USING CaRFG.

It is not necessary to add anything to the vehicle's fuel tank after
CaRFG is purchased from the service station. California regulations
require deposit control additives in CaRFG to avoid port fuel injector
and valve deposits.

OLDER VEHICLE'S PERFORMANCE USING CaRFG

Older vehicles are expected to operate satisfactorily on CaRFG
because these vehicles have been operating on gasoline similar to
CaRFG for a number of years. However, considerable testing indicates
that older, high mileage vehicles are more susceptible to fuel system
problems due to age and normal wear and tear regardless of whether
they are operated on conventional or CaRFG gasoline.

NOTE: Owners of older vehicles are encouraged to have their vehicle's
fuel systems inspected periodically and to follow their vehicle
manufacturers recommendations regarding vehicle maintenance.

ODOR EMITTED FROM CaRFG

CaRFG is not expected to smell different from gasoline most vehicles
currently use. If unusual odor is noticed, it is probably be from
oxygenates. Most service stations use vapor recovery systems to
minimize gasoline vapor release to the atmosphere during refueling.

Air Resources Board at the following toll free number: 1-800-922-7349.
