2000 Civic EX bucks at 3k-3.5k RPM
My 2000 Civic EX starts bucking around 3k rpm if I am under slow or
steady throttle. If am accelerating hard it does not do it.
The car also drops rpm and occassionally stalls at traffic lights. I
have changed the plugs and fuel filter to no avail.
Any ideas?

Knock off one other small, Do-It-Yourself, item: New air filter.
Does it do this only after the car is warmed up? If so, this symptom is
consistent with a failing distributor coil. Not sure the failing distributor
coil would cause the 3k rpm bucking, though.
How many miles on your car?

Condensation in the fuel system can cause these symptoms. Add a can of
"Heet" to your fuel tank and see if this helps.
This is the time of year, with temperature differences during night and day,
that fuel tanks should be kept as full as possible. This will help prevent
condensation.

There appears to be no pattern. Some times it will do it right out of
the garage in the morning. Other times it will do it after its been
running for awhile. Sometimes it doesn't do it at all.
It's driving me nuts.

Gasoline (in the USA) is already 10% alcohol. That's aproximately two 6
oz. cans of heet per gallon of gas.

Ok, I think I may have isolated a symptom.
The car ran great when it was at a half tank of fuel or less. As soon
as I filled it this morning, it started bucking at around 3000 rpm at
part throttle. It also drops rpm at stoplights and occassionally
stalls.
Any ideas?
Thanx.

Sorry if this is a repost, but I didn't see the original.

If a first Generation CR-V stalls at the first stop light before it's
warmed right up, the valves are about to burn, since they are too tight.
On the CR-V they need to be done every 50,000 Km.
I missed your mileage . . Any chance it's overdue for a valve
adjustment? I realize the engine is completely different.
