Hi
My 2001 v40 1.8 auto is a sluggish performer. It's not the GDI. Engine cover stamped Volvo not GDI.

It's driveable and usable. There are no OBD codes and no engine management warnings.
No smoke, starts on the button. Sits at 80mph fine. Auto box changes fine.
Service history shows VVT pulley recently replaced. Oil and coolant looks fine.

It's just a slow old hector pulling away, slightly worse when cold. Pulls better after 2500rpm.

Temperature gauge sits a bit low, and heater output is low. Not checked resistor jobby yet, as thinking I've got a slightly open rad stat. Hose to rad gets warm after a minute or two even when engine remains stone cold. So think stat is always part open.

Any thoughts on my sluggish performance?
