Hello,

My '00 Max has had a problem for a while where during cold weather (only) after start up it will stumble about every 10 seconds or so, for about 10 seconds, then clear up. If you try to drive it immediately while still very cold it will fall on it's face, barely accelerate at all, until it warms up a bit then it's fine.

I do have an EGR code (can't remember the number at the moment) and a rear O2 sensor code.

I don't think the O2 could matter during cold start but do you think the EGR issue would cause this or could it be something else?

Thanks,
Fred

EGR might have something to do with, but the rear O2 sensor should have nothing to do with it as it only checks if the cat is there.

Just put in new Iridium plugs so it's not that.
