2023 Mustang (CZG) Canada/United States of America, Vehicles Built From: 14-11-2022, enUSA, Edition date: 202209, First-PrintingTable of Contents

Even though the GT equipment groupintroduced in 1965 was again available fora final year, it was overshadowed for 1969,as the hot ticket was an all-new Mach 1model – wearing the name borrowed fromthose radical recent Mustang show cars.The new Mustang Mach 1 came standardwith the 351, a desirable mix of appearanceenhancements, plus special reflectivebodyside stripes and an uplevel interior.Later, a flat-black rear decklid spoiler anda set of rear window louvers were addedas dress-up options. To many enthusiaststoday, a ’69 Mach 1 equipped with anoptional new-for-’69 428 Cobra Jet V-8 isthe first true Mustang muscle car and atop-shelf collectible.
Other than yet another front-endfreshening (including going back to justtwo headlamps and adding non-functionaloutboard air inlets) and the elimination ofthe side scoops, the biggest change to the1970 Mustang lineup was a move to theCleveland-design 351 V-8 over the Windsor351 version from the year before. The GTmodel was dropped in the face of theMach 1's popularity, but the 428CJ engineoption was again available across theboard. By 1971, Ford’s famedfirst-generation pony car had alreadyundergone its fourth major facelift, growingin every dimension to accommodate evenbigger engines. The ’71 Mustang featuredan extended nose with a body that waswider, close to a foot longer and around600 pounds heavier than the original. TheSportsRoof-only Mach 1 model was nowFord's bread-and-butter enthusiast model,especially with the optional new big-block429 Cobra Jet engine, good for 370horsepower.
There were only minor changes on tap forMustang in 1972 and ’73, most of themdealing with the options list and thecontinuing emasculation of engineofferings and horsepower in the face ofemissions and fuel economy regulations,
as well as the elimination of a convertible.The automotive performance world sooncame to a screeching halt in the wake ofan oil embargo and resulting gasshortages, forcing most Americans toabandon their muscle cars andV-8-powered rides in favor of smaller,more fuel-efficient vehicles. Ford saw themarket shift as the perfect time to returnits pony car to its roots – a compact,affordable, sporty car whose styling andimage captured the spirit and imaginationof the American public.
When the new-from-the-ground-up,second-generation Mustang II waslaunched for the 1974 model year, it wasthe first Mustang equipped with afour-cylinder engine. An all-new 2.3-literI-4 produced around 90 horses as thestandard powerplant for the downsizedMustang II - yet performance was roughlyequivalent to the previous Mustang’s biginline six. The Mustang II was available asa hardtop two-door notchback coupe or athree-door hatchback-style fastback.Buyers had a choice of either I-4 or V-6power, as well as a three-speed automaticor four-speed manual transmissions. Tokeep Mustang’s performance image goingeven in a world where consumers favoredfuel economy over horsepower, anenthusiast-focused Mustang II Mach 1model was offered as a three-doorhatchback-style fastback, replete withbucket seats.
There’s little question that the saving gracefor the Mustang II’s performancereputation came when Ford finally realizedit needed to put the 302 V-8 back onto theMustang option list for 1975-78. The V-8was available in any model, but first onlymated to a three-speed automatictransmission, as a four-speed manual wasdelayed a full year until a suitable clutchcould be tooled up. The two-barrel 302shoehorned into the Mustang II gotcatalytic converters to help meet 1976’s

tighter emissions standards, and saw anincrease to 139 horsepower – nearly equalto the ’73’s standard V-8 power level. TheMach 1’s optional Competition Suspensionpackage offered stiffer springs, adjustableshock absorbers and fatter front and rearstabilizer bars to improve handling, andkept it a popular enthusiast choice over allfive years of Mustang II's production. Bythe dawn of the third-generation Mustang,the Mach name would not return again tothe Mustang line until some 25 years later.
After the 1979-93 Fox Body Mustang yearshad come and gone with the reintroductionof a GT model, new sheet metal on arevamped SN-95 platform helped torekindle consumer interest in afourth-generation Ford Mustang.Enthusiasts lavished their attention uponthe 1993-1999 Mustang Cobraperformance model developed by the FordSpecial Vehicle Team skunkworks group,while Ford engineers looked to specialtymodels to fill the mid-market slot betweenthe standard Mustang GT and theupmarket Cobra.
After the success of the 2001 Bullitt, anew-for-2003 Mach 1 was launched tooffer fans some design cues from its '69namesake, including a blackout hood,black front air-dam extension and reardecklid spoiler – even bodyside scoops. Tomatch its aggressive look and hardwareupgrades, the '03 Mach 1 was powered bya 305-horsepower, 4.6L DOHC modularV-8. Unlike the SVT Cobra, the Mach 1offered an automatic transmission optionin lieu of the manual, and consequentlydrew a new group of enthusiast buyers intothe Ford fold. The strong customerresponse prompted another year of Mach1 production for 2004, the Mustang's finalyear on the fourth-gen platform.
Thanks to a popular mix of appearance,features and power, the 1969-73 Mach 1'sproved to be everyman's muscle car, andhave earned a respected place in Mustangperformance lore. Beyond those classicyears, the Mach 1 carried over for all fiveyears of the often overlooked 1974-78'sbefore a hiatus that ended with themodern and muscular 2003-04's. Mach1’s return to the Mustang lineup for 2021will add a new chapter on modern-daymuscle for this beloved model, and willcement its rightful place near the very topof Mustang performance history.

On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as theon-board diagnostics system (OBD-II) thatmonitors the engine’s emission controlsystem. The system protects theenvironment by making sure that yourvehicle continues to meet governmentemission standards. The OBD-II systemalso assists a service technician in properlyservicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected amalfunction. Temporary malfunctions maycause the service engine soon indicator toilluminate. Examples are:
1.Your vehicle has run out of fuel—theengine may misfire or run poorly.
2.Poor fuel quality or water in thefuel—the engine may misfire or runpoorly.
3.The fuel fill inlet may not have closedproperly. See Refueling (page 155).
4.Driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank withgood quality fuel, properly closing the fuelfill inlet or letting the electrical system dryout. After three driving cycles without theseor any other temporary malfunctionspresent, the service engine soon indicatorshould stay off the next time you start theengine. A driving cycle consists of a coldengine startup followed by mixed city andhighway driving. No additional vehicleservice is required.
If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II maynot have symptoms that are apparent,continued driving with the service enginesoon indicator on can result in increasedemissions, lower fuel economy, reducedengine and transmission smoothness andlead to more costly repairs.
Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programsto inspect the emission control equipmenton your vehicle. Failure to pass thisinspection could prevent you from gettinga vehicle registration.
If the service engine soonindicator is on or the bulb doesnot work, your vehicle may needservice. See On-Board Diagnostics.
Your vehicle may not pass the I/M test ifthe service engine soon indicator is on ornot working properly (bulb is burned out),or if the OBD-II system has determinedthat some of the emission control systemshave not been properly checked. In thiscase, the vehicle is not ready for I/Mtesting.
If the vehicle’s engine or transmission hasjust been serviced, or the battery hasrecently run down or been replaced, theOBD-II system may indicate that thevehicle is not ready for I/M testing. Todetermine if the vehicle is ready for I/Mtesting, turn the ignition key to the onposition for 15 seconds without crankingthe engine. If the service engine soonindicator blinks eight times, it means thatthe vehicle is not ready for I/M testing; ifthe service engine soon indicator stays onsolid, it means that your vehicle is readyfor I/M testing.
