    As some of you may have read i had some issues last week which were resolved by changing one coil for a new on.

    Since then i have noticed a slight performance loss. car nolonger seems to pull as much as it did.

    My mate said changing all 4 coils should make a diff.? and also will need retuning after the new coils fitted.

    Is this the chase?

    What should i check?

    I wouldnt have thought so... did you leave the battery disconnected for any length of time? That usually resets the ECU and according to the guys here forces it to 'learn' again so could take a few weeks...
