Bottom Line Up Front
Car manufacturers stopped fitting manual chokes in new production models in the early 1990s, and electronic fuel‑injection systems took over the job of getting engines up to temperature.

Design & Looks: The Manual Choke’s Last Days
In the 1950s through the 1970s, a small lever or knob on the dashboard let drivers add extra fuel when the engine was cold. The part was simple – a plate that restricted airflow in the carburetor, making the mixture richer.
By the 1980s the look of the choke began to fade. New cars featured smoother dashboards and fewer mechanical knobs. The visual clue of a “cold‑start” lever became a relic of classic cars.
Performance & Mileage: Why the Switch Happened
Manual chokes were unreliable. If left on too long they could foul the spark plugs, raise emissions, and waste fuel. As emission standards tightened in the late 1970s, engineers needed a more precise way to control the air‑fuel mix.
Electronic fuel injection (EFI) solved the problem. Sensors measure engine temperature, air flow, and throttle position, then a computer tells the injectors how much fuel to spray. The result is faster starts, smoother idle, better mileage, and far lower emissions.
Most U.S. and European models switched to EFI between 1985 and 1992. Some Asian manufacturers kept the choke a bit longer for budget models, but by 1995 the practice was virtually extinct.
Price & Rivals: Market Impact of the Change
When EFI arrived, the cost of a new engine control unit was offset by savings in fuel and lower warranty claims. Buyers noticed the improvement in cold‑start performance and fuel economy, which helped newer models compete against older, choke‑equipped rivals.
Today, no mainstream car offers a manual choke. Even classic‑car enthusiasts who rebuild old engines often install electronic choke kits to meet modern emission rules.
Quick Reference Table
| Engine | Mileage (mpg) | Price (USD) | Top Features |
|---|---|---|---|
| 1970s V8 with manual choke | 15 city / 20 hwy | ~$3,000 (used) | Simple carb, cold‑start knob |
| 1988 2.0L I4 EFI | 24 city / 30 hwy | ~$8,000 (used) | Electronic fuel injection, O2 sensor |
| 1995 1.8L I4 EFI | 28 city / 35 hwy | ~$12,000 (used) | ECU, idle‑air‑control valve |
FAQ
When did cars stop using manual chokes?
Most manufacturers stopped installing them in new models by the early 1990s, with the last few budget cars dropping the feature around 1995.
What replaced the manual choke?
Electronic fuel‑injection systems, controlled by an engine computer, took over the role of enriching the mixture during cold starts.
Do any modern cars still have a manual choke?
No mainstream production car today uses a manual choke. Only classic‑car restorations or specialty off‑road vehicles might retain one.
