Hi,
I posted recently about my seicento having starting problems. I changed the Crankshaft sensor, which seems to have helped.
Now theres another problem. When the car starts, it runs at low revs for a short time (also revving up and down on its own), then suddenly revs high for no apparent reason? When you disconnect the TPS sensor the revs drop down and the engine runs quite smoothly.
Any ideas?

Throttle cable too tight and/or map sensor air leak.

Cheers

PD

Yeah, I have the same car and mine revs up and down on its own also known as hunting?? not sure why it does it.
