    Default Acceleration problem Z22SE

    Hi,

    I have a problem on my Z22SE SRI (2003-08 make) dont know if it is a problem maybe it is usual and normal.
    When changing from 1st to 2nd fully accelerating it feels like the acceleration is laggy and it takes some time like a second or two to pull. It doesnt happen from 2nd to 3rd etc
    Ive done only the airbox mod everything else is standard/genuine
    Any ideas?

    Is it definitely a Z22SE and not a Z22YH mate, there both in the Vec with only small differences.

    did the yh not start on a 55 plate ie the direct every direct i have heard of has lag problems was that not the start of the facelift u say takes a sec or 2 mine is rather laggy if ur not giving it some beans wen get by the 2-3k revs i starts to move alot faster ie more responsive think its a common trait of the 2.2s prob the only way to solve the lag would be a remap

    The YH started in the vec on a 54 plate and from launch on the estate and signum. With the op's car being from over the water however fitment could be different. I dont know mate really, does it feel like a misfire? Have you looked to see if the intake track all clean, the tb's tend to get all gunked up with the combination of the cam breather and egr.

    doesnt feel like a missfire or so. Just a lag switching throught the gears
    Seems like it is a common trait for Z22SEs with their electronic throttle control it is annoying but i can live with that what to do. The remap is not worth the money and what yuo get for that just need to check the fuel filter (oh yeah haven't changed it yet since i bought the car 2 years ago..shame on me) intake track etc.
