Things point towards manifold pressure transducer, or its connecting
hose. Mind you, faulty transducer should produce codes. Other cause
could be loose clamp on exhaust M to WG hose, although this usually
produces cut out rather than just spluttering, but it gives no codes. If
you haven't already, frequency valve circuit should be also checked.
