    Vehicle : SRI 150

    Trim : Smart and Bad!

    Engine : Z19DTH

    Year : 2008

    Mileage : 105000

    Default SOLVED! Limp while driving

    If u recall, i had issues loosing power while driving, uphill or downhill, after roundabout or accelerating then releasing all caused limping, 30 seconds all back to normal.

    Finally solved...

    Intercooler hose was tight but not enough. Bought better quality clips and tightened it all up with new hoses. Woohoooo.

    Next to do list...

    DPF pass thru,
    EGR full blanking (currently oval blanked (exhaust end)
    Then delete from ECU
    REMAP!

    What else can i do?? To really improve the engine.

    The blue sticker one.

    The swirls move perfectly works the same as the car i took pictures of.

    What else should i look for to stop lag under 2k as the car i took pictures of have the boost from idle.

    wife's dad's car kick in from rest! this made me realised that we need to find what causing the problem. i have done the EGR it is tight. even disconnected and no changes. i did the throttle body disconnected before with no change.

    What else could i do???

    All boost hoses are all perfect. just been changed yesterday. the vaccum hoses all replaced. the BCS (Boost Control Solenoid) been refurbed (nout wrong but refurbed anyways)

    Still at a loss!
