Ok I've found this product which can clean all the carbon deposits in the engine, fuel lines and crank case, it can improve MPG, throttle response and idling. I just need help as 1/3 goes in fuel tank, 1/3 into crankcase and 1/3 into the engine through the intake manifold, but we have to use a vacuum hose that goes into the intake manifold for it to clean the engine, people have been advised not to put it through the throttle body. I've got a 1.2 8v 1997 corsa b merit. Any Brake booster lines in these corsa's? lol

to be honest, dont bother.... just throw it in the fuel tank.
