    Vehicle : SRI 150

    Trim : Smart and Bad!

    Engine : Z19DTH

    Year : 2008

    Mileage : 105000

    Default Slow power when under 2000,

    As above. Since i changed fuel filter the old one sodden black, replaced with new white filter in. Filled it up with fuel before securing the screw cap and fitted. Started after a few turning, no issues, no fuel leak. Done job well. This was yesterday.. Took car for a drive today feels a bit off power is weak under 2k til it reach 2000 turbo kicking in and opphhhhh as it should.

    Coolant issue as its leaking out of the system somewhere! Car booked in monday for a closer inspection from well known and good reputation garage which means my bank balance will be down faster! As people say. Expensive means best job done than cheap and problems

    Is there any links?

    I know egr valve is fine, booster sensor is spot on, i know there is a split in intercooler hose but good for the oopphhhhh really but under 2000 revs? Like its a slug. Might be cos its cold out??

    Cold air gives more power as it is denser and therefore more air can be squeezed in and more fuel bigger bang and all that jazz. After all that's why we have inter coolers.

    The split in the intercooler house is the problem because its not meant to be there!

    Its lettting the power out and it would be a good idea to replace it

    I will replace but cant find the hole. But why it feel like not much power when i put foot down under 2000? Slowly build power til 2000 revs when turbo kick in. Cant be fuel filter causing that can it? Or need more miles for it to be properly absorbed and flowing better? Or am i missing something else? The boost hoses are holding til i go 60mph or over heavy footed but manages ok sensible footed!
