Several people have mentioned sluggish performance, pinging, and generally blah performance.
Our cars accumulate carbon, due to the EGR reflux, the leaky valve stem seals, and leaky rings, which stack up over time.
The best cure for this, other than a brand new motor, is seafoam.
Before you start, you need:
Oil and filter for oil change
1 can of seafoam
To properly do this, you start with a warm engine.
Pull the brake vacuum line off, carefully, while the car is running. stick it down into the can, barely sucking any into the line. Do not feed it enough to hydrolock your engine. you may have to manipulate the throttle a bit to keep it running.
keep going until the can is half full, or slightly less, then dunk it in deep, killing the engine with the liquid. Please don't give it a cylinder full at once, that will be bad.
Leave it for 15 minutes; Pour the remainder of the seafoam into the oil. The oil will come out black as hell. After 15 minutes of soak time, start the car.
If you have done it correctly, when your car starts it will Smoke like a motherfucker, and fog the entire neighborhood. Warn your neighbors beforehand, you don't want the FD showing up. It smells like damp kerosene. It goes away quickly.
Change your oil, all the crap that didn't go out the exhaust is in the oil.
Take your car for a drive, and drive the rest of the carbon out.
