Question about 1999 Pontiac Grand Prix
Like new? not hardly, but it will, if used in the gas tank on a regular basis, and if it is induced through the intake by sucking it through a vacuum hose will clean the top end of the engine of unburned fuel, and can help with rough idle, and can free sticking valves. It is better used as a maintenance item, it will not fix mechanical faults.
