There is another thread on these forums that suggest to try REV X. I personally haven't used it yet. If you read that thread they say it helps with the cold starts by cleaning the injectors I do believe. As for the oil leak I would get up in under and wipe everything down to make sure where it is coming from.

I suggest fuel additives and oil additives to try to resolve the problem. I am going through a similar problem on my 03. Seems to be getting better.

Do you have the latest heat inductive pcm/ficm calibration?

[fbelz]

I had the the latest things calibrated in. Will do the oil additive thing tomorrow and see how that goes.

Thanks
