Chrysler was mostly done with carbureted cars by 1990, with the exception of the Jeep Grand Wagoneer, which kept a carbureted engine until 1991. While it is unclear what year Chryslers had plastic carburetors, it is known that plastic parts were introduced to engines in the 1950s, with plastic being used more extensively in engines in the 1960s. By the 1990s, carburetors were largely replaced by fuel injection for cars and trucks.

What You'll Learn
Chrysler was done with carbureted cars by 1990
By the 1990s, carburetors had been largely replaced by fuel injection for cars and trucks. Chrysler, in particular, was done with carbureted cars by 1990, though it kept a carbureted engine in the Jeep Grand Wagoneer until 1991. In 1994, all passenger cars sold in the United States had some form of electronic fuel injection, except for one: the Isuzu Pickup.
The move away from carburetors began in the 1970s when fuel injection was increasingly used in luxury and sports cars. By the late 1980s, fuel injection had become standard in Europe, and by 1990, it was becoming the norm in the United States as well. This was partly due to EEC legislation requiring all vehicles sold and produced in member countries to have a catalytic converter after December 1992.
While Chrysler may have been ahead of the curve in phasing out carburetors, other car manufacturers also made the switch around the same time. For example, Hyundai switched to fuel injection in mid-1989 for its 1990 models, and Honda adopted fuel injection for its 1991 Prelude model.
While carburetors may have become obsolete for cars and trucks, they are still used in small engines, such as those found in lawnmowers, generators, and concrete mixers. They are also still widely used in piston-engine-driven aircraft, where they pose a unique challenge due to the potential for ice formation during descent.
As for the use of plastic in carburetors, there is some evidence that it was used in Briggs engines, with one source mentioning a Briggs engine from December 1956 that had a plastic choke lever. Additionally, some early plastics like Bakelite were used in ignition parts. However, there is no specific mention of Chrysler using plastic carburetors.

Jeep Grand Wagoneer had a carbureted engine until 1991
The Jeep Grand Wagoneer was produced from 1963 to 1991 and was the first luxury SUV. It was widely considered to be the first sport utility vehicle and was far ahead of its time. It featured an overhead cam engine, optional independent front suspension, and optional air conditioning. The Grand Wagoneer was one of the last carbureted cars sold in the US, with a carbureted 360ci V-8 engine that dated back to the 1970s.
Chrysler bought out American Motors Corporation (AMC) in 1987 and left the Grand Wagoneer largely untouched, even continuing to build the model with the carbureted AMC V8 engine instead of its own more modern fuel-injected V8. The 1989-1991 models are considered the "best of the breed" due to many improvements, including a quality replacement for the earlier, leak-prone air conditioning compressor, the addition of a rear wiper/washer assembly, and a general improvement in fit and finish. An interior overhead console was also added, featuring brighter map lights, an outside temperature sensor, a compass, and a storage compartment for sunglasses.
By 1991, the Grand Wagoneer was the longest-running domestically produced vehicle on the same platform, but sales had plummeted due to the 1990 oil price shock, which raised gasoline prices in the US by 11% in less than a year. On February 27, 1991, Chrysler announced it was ending production of the Grand Wagoneer, making it the last mass-produced vehicle without integrated air conditioning.
In the US, the last cars using carburetors were the 1990 Oldsmobile Custom Cruiser, Buick Estate Wagon, Cadillac Brougham, Honda Prelude (Base Model), and Subaru Justy. The last car with a carbureted engine was the 1991 Ford Crown Victoria Police Interceptor with a 5.8L V8 engine. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, but they are still used in small engines and motorcycles.

The 1991 Ford Crown Victoria had a carbureted version
The Ford Crown Victoria is a line of full-size cars that was manufactured and marketed by Ford from 1980 to 1991. The 1991 Ford Crown Victoria had a carbureted version. In fact, it was the last car in the US to be sold with a carburetor. The 1991 Ford Crown Victoria was also one of the only cars to have steel bumpers and airbags concurrently.
The 1991 Ford Crown Victoria was the last model year for the LTD Crown Victoria, with its rear-wheel drive and carbureted H-O 351 cubic-inch V8. The carbureted 5.7-litre motor was already in place in the LTD Crown Victoria, which was especially popular when equipped with the Police Package (aka Interceptor). These cars came with everything heavy-duty, making them more durable for police departments and the highway patrol.
The 1991 Ford Crown Victoria was also the last model year before the car was replaced by the redesigned Ford Crown Victoria (dropping the station wagon body style and the LTD prefix). The redesigned model underwent extensive body, chassis, and powertrain upgrades, remaining in production through 2011.
In the 1990s, carburetors were largely replaced by fuel injection for cars and trucks, but they are still used by some small engines and motorcycles. In addition, they are still widely used on piston-engine-driven aircraft.

The 1994 Isuzu Pickup had a carbureted base-level model
The Isuzu Pickup is a rugged and durable truck known for its power and performance. The 1994 Isuzu Pickup had a carbureted base-level model, which was equipped with a carburetor to mix the correct amount of air and fuel for efficient engine combustion. Carburetors have been used in vehicles for a long time, and while they are still found in some small engines and motorcycles, they have been largely replaced by fuel injection systems since the 1990s.
The 1994 Isuzu Pickup with its carbureted engine delivered a powerful and reliable performance. The carburetor played a crucial role in the vehicle's overall functionality by ensuring the precise mixture of gasoline and air. This mixture was essential for the engine's combustion process, providing the necessary fuel and oxygen combination for the engine to run smoothly.
Isuzu, known for its quality and innovation, designed the carburetor in the 1994 Pickup to be a straightforward unit. This design allowed for easy maintenance and repairs, making it convenient for owners to keep their vehicles in optimal condition. The availability of rebuild kits, such as the 1994 Isuzu Pickup carburetor rebuild kit, further simplified the process of maintaining and restoring the carburetor to its original functionality.

Plastic carburetor parts were used in engines from the 1950s
A carburetor is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. Carburetors have been largely replaced by fuel injection for cars and trucks since the 1990s. However, they are still used in small engines, motorcycles, and piston-engine-driven aircraft.
In the 1950s, plastic carburetor parts were used in engines, specifically by Briggs & Stratton. A user on the Smokstak Antique Engine Community forum noted that their Briggs & Stratton engine, with a serial number indicating it was made in December 1956, had a carburetor with a plastic choke lever. Another user on the same forum mentioned that Briggs used plastic air vanes in their air vane governors in the 1950s, interchangeably with sheet metal ones.
Plastic carburetor parts were also used in other engines during this period. Chevrolet, for example, used plastic (nylon) lined cam gears in the 1960s, which were said to be good for 100,000 miles. Additionally, some early ignition parts were made of Bakelite, an early type of plastic.
The use of plastic in carburetor parts during the 1950s and beyond showcases the evolution of engine design and the search for more durable and efficient materials.
