I just finished doing the head gaskets on my 04 Disco and everything went well but when I start it cold, it idles really low. Before when I would start it cold it would idle at around 1200 and then drop down and now it is around 700ish. it idles smooth and not missing at all. Any suggestions??? I cheched all connetions and everything looks good. I do have a small leak around the SAI pipe but have another on the way to replace that. Thanks Jim

 

How about fault codes, if so what are they?
Any white smoke on cold starts?

 

Thanks Mike for the quick reply....no I have got no fault codes and no smoke of any kind.

 

Your idle air control is out of whack, give it a weeks worth of driving to reset itself.
If it does not re-adjust then you will need it reset.
Make sure it is plugged in to.
