on the diag computer does it log up dephasser fault or 
thoothed belt error.
if so it requires a new dephasser pulley, timing belt and
camshaft sensor. this requires a specialist fitting as it is not just a case of putting a pulley and belt on. as valve damage can occurr.
 if it does not have the above faults remove vacuum pipe on the throttle body and spray with carburretta
 cleaner .refit pipe and start with full throttle
