Replaced the IACV and the problem is still there.

Any other ideas?

Try the following: turn on ignition and wait 5 secs, you may hear fuel pump prime, turn off ignition and back on, wait a couple of seconds before cranking. The fuel pump will prime twice if you do this helping to build up fuel pressure and if that starts better then could be the fuel pump objecting to the cold.

Ok, so put back the original IACV and reset the idle. Startup problem still there.

The startup problem is getting worse 3-4 turns and the car won't start.

Replaced the battery last night and this issue still there this morning.

Things I think it may be:
1) bad earth - will test this theory later
2) Bad plugs - not sure if they would cause this symptom
3) Bad coils and/or leads - again not sure if they would cause this issue but I do have a slight miss under acceleration also.

Has anyone any other 'theories'?

Thanks.

The start issue is continuing to get worse.

Have tested if it is a bad earth but that's not the issue.

Haven't checked the plugs or coils yet.

Is there anything else this could be?

Is this still an issue? Having played with startup settings on my ViPEC it is quite sensitive to mix when cold so that could be a problem. The IAVC idle control has quite limited range so it relies on the various other "static" settings to start easily.

Any other symptoms once started and warmed a little or otherwise perfect?

You might find new plugs make it slightly better when they are super clean but will probably be short lived once plugs bed in.

Is it getting worse just because its been colder recently?

Yeah it's still an issue. The startup is getting worse. Before it would start and struggle and then start, now it is taking 4 or 5 to start: start/struggle/start (almost)/struggle/start (almost) and so on

The other symptoms are that the engine seems to be laboring and appears to be running rich - have had a quick chat with a local specialist (waiting for him to get back to me on taking the car in). There is an intermittent hesitation and the car is down on power.

Will take out the plugs this week and check the MAF (I'm not driving the car at the moment as a result of the issues.

Sounds like a more general problem than just the cold. Could still be something simple so good luck at the garage, hope you get it sorted soon.
