Hi,

I have a 2004 Honda Civic and lately I've been noticing a problem.

When I start the car in the morning it putters like it's running rough. I'll push the gas and it smooths out the puttering. I can tell you I had the tune-up done at 168,000 km and now the car has 192,000 km. I've had all of the engine belts changed as well. I haven't had the air cleaner element changed since 144,000 km. I don't live in an area with high soot or dusty conditions.

Any idea of what the problem might be?
