If your car has
- Poor fuel responses
- Lost its "power"
- Low RPM
- Lower top speed
- Burns a lot of fuel
Then it could be because of carbon build-ups in your engine's
combustion chamber. This is left behind with unburned fuel. It causes
poor acceleration, a loss in power, lower top speed, and burns more
fuel than it really has too. Not to mention causes smoke belching.
The best way to get rid of that would be to have a carbon ridding solution injected into
the combustion chamber. The solution will liquify the carbon and other build-ups,
which would then restore the "power" of your car. You'll get better
acceleration, higher rpm and top speed, save fuel, etc. have a mechanic do it for
you. It's alot cheaper and faster than having the engine overhauled (overhaul could trigger "loose compression").
