Just unplug the TPS and drive to see if that's the issue - I doubt it given the symptoms though, but quickly and easily proved.
The ECU compensates very well to the TPS being unplugged, to the point I didn't realise I'd left mine unplugged on my 205 GTi-6 for a few days! You can test to see if a few other sensors are the issue by unplugging them one at a time and forcing the ECU to revert to a set of default values, in much the same way as people do for the MAF on a HDi when they're playing silly buggers.
Faulty MAP sensor would be my guess if it does it from cold (as the lambda won't do anything until the engine warms up)
