1989 Chevrolet G20 problems
The Chevrolet Van or Chevy Van (also known as the Chevrolet/GMC G-series vans and GMC Vandura) is a range of vans that was manufactured by General Motors from the 1964 to 1996 model years. Introduced as the successor for the rear-engine Corvair Corvan/Greenbrier, the model line also replaced the panel van configuration of the Chevrolet Suburban. The vehicle was sold both in passenger van and cargo van configurations as well as a cutaway van chassis that served as the basis for a variety of custom applications.
Produced across three generations (1964–66, 1967–70, and 1970–96), the model line was sold under a wide variety of model names under both the Chevrolet and GMC brands. The first two generations were forward control vehicles (with the engine placed between the seats); the third generation adopted a configuration placing the engine forward of the driver. The second and third generations shared powertrain commonality with the C/K pickup truck model line.
After the 1996 model year, GM retired the G-Series vans, replacing them with the GMT600-platform Chevrolet Express and GMC Savana.

- Rough Idling and Stalling When Hot:
- Another common problem with the 1989 Chevrolet G20 van is rough idling and stalling when the engine is hot, especially after lightly tapping the gas pedal.
