Low revs hesitation when cold..?

[humpy]

When cold, I have noticed over the past few mornings that the car (2002 2.5) hesitates (sometimes almost stalling) when applying throttle when pulling away and moving up through the gears in low revs. I am getting it checked out, but thought I would ask if anyone has had anything similar and if so what caused it..?

Mine hesitated under full power only a while back and it was the coil, but it doesn't really sound like the same problem TBH.

Lambda sensor would be my guess.

I hope not I've recently had two new ones (second pair in 6 mths) fitted when I had new manifolds as a precaution (been there before with a lunched turbo) Unless there's a malfunction.

Investigations are underway.

Check the black square connector blocks. They get full of water and corrosion.
