With no other description of the car or problem it could be anything from a bad air filter to little green men stealing your sparkplugs.
worn parts.. particularly... pistons, piston rings, and the chambers...
when those are wore... you lose compression, thus loss of power..
nothing wrong with the car. it just has over 200 grand miles.
lost compression FTW
so if you replaced those parts, the engine would perform like a new engine?
If you do not know what replacing those parts will do for an engine, you should not replace them.
mainly compression and carbon build up
compression loss = power loss. Can't get around that one, even with additives that say 'miracle' somewhere in the title.
it is a systemic thing. The FI system is not what it was, the ignition, tranny, rings, valves.
add em up and it = something less.
You may have a broken or messed up <insert part/system here> that would bring most of it back.
What makes you think there is nothing wrong with it? If you have all of a sudden noticed a drop off in power there is something wrong with it. The compression ratio is going to be a extremely slow drop off over the life of the engine and you aren't going to notice a power drop off unless something major goes wrong.
If the car uses a timing chain and it has never been replaced in 200k miles it will be pretty stretched. Like the cylinders it would be a gradual thing but if the chain has stretched enough it could jump a tooth and that would cause a very noticable change in power. Then there are just all the normal tune up parts.
you could always take the car to a trusted mechanic and have the engine overhauled.
