The car drives fine. New spark plugs. But I lose power during accelaration. Could it be a fuel filter issue? The car has 340 000km and I drive 230km a day for work. I have always done proper oil changes at every 5000km's. No warning signal or engine light is on so far.

 

yeah i think its the fuel filter cuz my friends truck was doin the same thing and once he replaced that it stopped loosing power during acceleration....

 

You say KM so I bet you're not in USA.
USA Accord doesn't have a fuel filter, since 1998. Only an inlet screen inside the tank.
Canada is probably the same? Rest of the world, I have no idea.

 

Thanks for info. Hopefuly I can fix this

 

You can check however the fuel pressure, somewhere on the forum were directions on how to build you own fuel gage, or you can just buy a cheap air pressure gauge, a t fitting and some fuel hose and clamps, and put it together in a few minutes.
I used one for years on different cars and came pretty close to book pressure values. On my 99 i just opened the fuel line at the firewall and got a larger "adapter hose" that went over the fitting - does not have to look nice and you make your own adapters.

 

You might need to change your headers. because i have a 1998 Accord with 260 000KM. and after i changed the headers. i felt a big difference.
