156 1.8 ts - Hesitancy under acceleration?
Any ideas on this one?
Under acceleration there seems to be a huge flat spot in the power band between 3000 and 4500 in all gears but mostly in 2nd and 3rd.
I thought it might be the clutch slipping but it feels more engine related than drivetrain, if you know what i mean.
It pulls fine up to 3000, the VVT kicks in and then it's like the car is being held back with an elastic band.....above 4500 it's fine again usually.
I'm not talking foot-to-the-floor acceleration either, normal progressive inputs have much the same effect..
Any idea where to start looking to solve this? I assume if it was a compression problem it would be noticable right through the rev band?
