    Hi I have a Volvo 940 (1991 turbo model)

    It starts first time every time but today it seems to have lost a lot
    of power. The turbo kicks in but seem to stutter (best way I can
    explain it)

    It will only go upo about 75mph whereas it used to do over 100 with no
    probs.

    Is the turbo broken or is there something else wrong with the car?

    Does the boost guage go up normally? If so then the turbo is fine.

    I've seen several things cause this problem, fuel pressure regulator,
    air mass meter, split in one of the air pipes or couplers between the
    turbo compressor, intercooler, and throttle body. Clogged catalytic
    converter can cause it too. Do you get black smoke out the exhaust when
    you accelerate heavily?

    smoke
