Cold Startup Problem

[vwsaxon]

Hello all, well ive got rid of most of my codes on vectra now and its running alot better. Ive done, MAF, EGR valve, o2 sensor and given it a service. Its now not kangooing around but i still have my startup problem, ive done a little video which probably isnt the best video but im not revving it, its doing it on its own and when it drops below 1000 revs its spitting and back firing.

After about 30 seconds its ok and is fine for rest of day, its just cold startup.

Any ideas? Ive got one last code which is P0170 Fuel Trim Malfunction (Bank 1)

Whats my next move? Its a pain as you cant do anything for those 30 seconds, not driveable.

Cheers in advance

Ok i was having a chat with my friend last night whos pretty into vauxhalls and he asked me about the temp gauge, now it hardly moves on mine...could this be the problem afterall a thermostat?

You think its worth getting a new thermostat and temp sensor valve?

Is there ANYONE who can help me with this please?

Ive just changed the temp sensor valve and its STILL the same

Stick some fuel cleaner through an take it for good run. Nice Italian tune up see if that helps.
