    Lag when accelerating...

    Guest-only advertisement. Register or Log In now!
    Well since i got the car i always felt there was a lag, i'm not sure if this is common or not, but the other day i came to a stop sign, fully stopped, and i pushed the pedal all the way down, for a few second the car didnt move but then all of a sudden boost kicked in and it had crazy pick up.

    So my question is, is this lag normal or is something wrong? I have an exhaust leak if that would make a diff. and how do i fix this lag?



    Thanks

    because if i push the pedal lightly after a few seconds it picks up real slowly but if i push it harder there is much more pick up, and the needle climbs up quick

    Do not bring your car to the mechanic. As far as I can tell, nothing is wrong with your vehicle.

    At what RPMs is your turbo at full spool? A turbo just does not grant power as soon as you step on the gas, it needs to build pressure first then release it. These cars are built for driving at higher RPMs. If you drive in the lower RPMs, don't expect the turbo to kick in. If you feel the turbo kick in ~3500rpms then it is doing it's job properly.

    Oh, and get that exhaust leak welded shut (should not be more than $50). Or better yet, try and get an aftermarket Cat Back Exhuast. You could usually find used ones for cheap. I know I did.

    try this.. drive in second or third gear, and just cruise till you get up to 3000 rpms, then stomp on it

    It will just downshift. Sounds like he has an automatic.
