Chevrolet P300 problems
The Chevrolet Step-Van (and its badge-engineered counterpart, the GMC Value-Van) is a multi-stop truck made by General Motors from 1940 to 1998.
Dubl-Duti
The first generation of General Motors multi-stop delivery van was called the Dubl-Duti, introduced in 1940. The van was built on the 115-inch (2,921 mm) chassis of the Chevrolet pickup truck, with a body built by Divco Twin. The Dubl-Duti van used the same 216.5-cubic-inch (3.5 L) "Thriftmaster" six-cylinder engine as the pickup and Chevrolet passenger cars, but with a single-barrel updraft Carter carburetor rather than the downdraft Rochester unit used in other Chevrolet trucks.
The Dubl-Duti was restyled in 1941 to suit the new Chevrolet AK Series truck body. Despite the "Advance Design" trucks being released in calendar year 1947 as a 1948 model, the AK Series-based Dubl-Duti continued production for another year thereafter.
A new generation of Dubl-Duti was introduced for model year 1949, with two different wheelbases shared with the medium-duty Advance Design pickup trucks: the model 3742 with 125+1⁄4-inch (3,181 mm) wheelbase, and 137-inch (3,480 mm) log model 3942 . The "Thriftmaster" engine was carried over for the 1949 and 1950 model years, and replaced for 1951 by the 235.5-cubic-inch (3.9 L) "Loadmaster" engine. The Dubl-Duti ceased production in 1955.

One common problem with the Chevrolet P300 is the P0300 code, which indicates a random or multiple cylinder misfire detected. This issue can be caused by several factors, including ignition system problems, fuel delivery issues, engine mechanical problems, sensor issues, wiring problems, emissions equipment issues, computer problems, and vacuum leaks.

Fuel delivery issues, such as a weak fuel pump or clogged fuel injectors, can also trigger this code. Engine mechanical problems, such as a failed head gasket or loose timing chain, can also cause the P0300 code. Sensor issues, such as a bad mass airflow sensor or crankshaft sensor, can also lead to this code. Wiring problems, such as a broken wire or loose connector, can also cause the P0300 code. Emissions equipment issues, such as a bad exhaust gas recirculation valve or secondary air injection system failure, can also trigger this code. Computer problems, such as software in need of an update or faulty hardware, can also cause the P0300 code. Finally, vacuum leaks, such as a damaged vacuum hose or a leaking intake manifold gasket, can also cause the P0300 code.
The symptoms of the P0300 code can vary, but they often include a check engine light that is illuminated, engine performance problems such as hesitation and lack of acceleration, hard starting and extended cranking, shaking and jerking as the engine stutters, reduced fuel economy, and a failed emissions test.
To diagnose the P0300 code, you should look at all possible causes and use a professional mechanic if you don't have the required DIY auto repair experience and skills. To fix the P0300 code, you may need to replace the spark plugs, repair or replace the fuel pump, clean or replace the fuel injectors, repair or replace the head gasket or timing chain, replace the mass airflow sensor or crankshaft sensor, repair or replace the vacuum hoses or intake manifold gasket, or update the software or replace the hardware in the computer.
