Re-Program/Replace ECU ?

Hi Guys,
I have an Civic 2000 Exi (Automatic with the D15Z4 Engine). Not much power but it's supposed to be very fuel economical. But mine isn't. So i took it to the agent and a few other experts to check what the issue was & finally the agent plugged the Diagnostic Computer & did a full check.

They said the Injectors are opened for too long (when idling it should be around 2.7 - 3.1 ms) but mine is around 3.5 - 3.7 ms and there is nothing that they can do....


What are my options ???

Re: Re-Program/Replace ECU ?

are all the injectors spraying like that or just a few? You can take them out and have them bench tested and flow matched.
