Hi Mate,
This problem seems like an epedemic because my engine is doing the same damn thing!
Someone suggested plug / HT leads..
check out my thread 'Omega V6 misfire' hopefully we will get past this.
Regards,
Stephen

Do you have oil in your spark plug wells? Have a cam cover oil leak?

Lambda sensor problem would give you an EML light on .. as you don't have that my guess is HT problem .... :(

Have you done the paperclip test ?
