An engine decarbonizing system comprises a manifold with one central and four lateral bores. Pressurized air and decarbonizing fluid in separate containers are adapted to be co-mingled and fed to and through the manifold. A tube assembly has an output tube and two parallel input tubes operatively coupled. The output tube is coupled to the central bore and the two parallel input tubes are coupled to the containers for dispensing pressurized decarbonizing fluid. Four short tubes are coupled to the lateral bores and second ends have a rigid cylindrical nozzle selectively positionable within a spark plug for the delivery of a spray of pressurized decarbonizing fluid. Four switches are coupled to the manifold adjacent to the interface between a short tube and a short bore for selectively allowing or precluding the flow of decarbonizing fluid.
