Hi Guys.

When I drive my car first thing in the morning, it runs a little sluggish and hesitant at slow speeds, but after 30 secs or so the car runs and responds fine as if she's warmed up a bit.?
It doesnt stall and idles fine and there is no dash light etc. I have changed the MAF recently, however with the old MAF the symptoms were just the same, so I think I can rule that out.
Could it be the upstream oxygen sensor?
Anyone else have this problem?

Thanks

Yep, happens to me. I always say it feels like massively increased engine drag, but I think we're talking about the same phenomenon.

yeah it has never got worse but does happen each day near enough for 30 secs. Do you think its anythin to do with crank position sensor? oxygen sensor?

You know, mine isn't that consistent so I've never given it much thought. I'd say I notice is less than once a week.
