Can all the learned folk offer me some advice with my Bosch MFI.

Its a 2.4S that was starting and running well but blowing smoke. Decided it was running too rich so had some idle and pump adjustments done. Bad mistake. All I have now is a car that runs very roughly when cold, backfires when cold and at constantly at higher speeds when changing gears. Can't seem to return to where I started from.

Yes, I know now we should have made notes how many notches both were changed. Car runs well after its warm, smoothly and with good acceleration.

Are we thinking pump problems that were hidden the the rich mixture originally or have I just stuffed up the settings now given that the car still runs well despite the constant backfiring i.e the pump is ok


Thanks
