C70 Hesitation

Afternoon People. New to this forum and new to Volvo's. Bought my first, 1999 C70 2.4 Turbo GT in January this year (2005). Recently, whilst travelling down the motorway, the car would 'hesitate' at several different speeds, namely just over 50mph and then again at just about 72mph. Head gasket has NOT gone. Had plugs replaced (with platinum etc), new leads, distributor cap and rotor arm but the problem still seems to be with me. Any ideas? I'm thinking fuel pump, dirty injectors or dirty air filter. Help?

Thanks, Simon.

Throttle body gungy (needs a clean).

Fuel pump relay.

To add to the list of things you've considered / tried...

I would be tempted to check the gap on the spark plugs.
Also *may* be:
Dirty air filter, dirty fuel filter, software problem, or may be a dodgey BCS (Boost Control Solenoid) or a sticky wastegate.

Maybe get the codes read and see if anything comes up.
