 Do you remember where you bought the redline. I went to 2 auto stores and
they had both never heard of it. BTW, I'm in Sydney Australia.

Thanks
John

Do not spray brake cleaner in your manifold. You kept saying 'carby' did you
mean Intake Manifold? Is your car fuel injected? The thing is you have this
little device called an O2 sensor, and brake fluid will probably F it up,
its not meant for to use that way. Water indeed can clean off carbon from
the engine, the best results from using water though is to use it regularly
on a water injection system. You probably don't need to go that far, though.

What I would do is pick up a can of 'seafoam' Find a vacuum tube on your
manifold and let it suck some out of the bottom half of a Styrofoam cup. Let
it suck just a few seconds until the car starts to stall, then let it go.
Beware that this stuff causes a *massive* amount of smoke to pour out your
exhaust for a good 10 minutes, remember...*massive­* If you can't find a
vacuum hose or don't want to do it that way, simply take off your intake
hose and spray the seafoam directly into the manifold.

One other thing to consider is this. If your car has a catalytic converter
and your engine has a real bad carbon build up, there is the possible chance
your converter is close to being useless or already is. The seafoam will
clear all that junk out and may end up causing converter problems, some
people have actually seen the carbon build up shoot out the exhaust tips.

The best advice is to keep your car regularly maintained by spraying a bit
of seafoam or water into the manifold every oil change, just a bit should
help. Do the seafoam at your own risk! If you want more info just Google it
you will probably find a ton, also do NOT use seafoam on a rotary engine.

 there are no carbs on saturns
carb cleaner cleans throttle body do it while car is off to avoid mixing it with oil
but even with car on with no throttle applied it will stall the car anyway
but as far as cleaning carbon build up just use marvel mystery oil/ its a great upper cylinder lube put some in the gas tank some in the oil and slowly pour some into the throttle body at about 1/8 throttle or just enough to suck it in and not stall the car.
i have noticed ALL saturns burn oil they do it because the piston rings get carbon build up around them very quickly poor design by saturn after it burns enough oil the spark plugs get filled with nasty black oil deposits and simply foul out like a 2 stroke dirtbike with the wrong jets running way too FAT or RICH.
THE MARVEL MYSTERY OIL breaks up the carbon stuck to the rings and valves and all other parts quickly the rings begin to seal the cylinders again giving more compression
and less oil blow by better fuel economy more power and longer lasting spark plugs
i use it every oil change because i have 200 k on my 95 sl and she gets 31 mpg and runs smooth as could be.
