Hello clever people

I seem to have a lack of power problem on my 156 JTS. And I have feeling it could be the cam variator not tunrning on at the right moments..
The car is happy to rev up until 4000rpm, after that i kinda slows down and takes ages to reach 6000rpm.


I hooked up Fiatmultiescu and went for a drive.

The cam variator turns on at 2500rpm and then turns off at 3500. I tried at different speeds. All the same.

Shouldn't the cam variator stay turned on for longer?

Ive got about four good ones kicking about. But they are from a ts engine. So not sure they would yeild better results.

That's what happens when the car runs rich be default. But you should see similar results with better fuel consumption with a new maf.

Do anyone know the Bosch number for the sensor itself used in 0 280 218 113?
It could be that the sensor also is used in some cheaper MAFs

I have one here. I paid 850 dk kr for my Bosch maf. But there is something wrong.

It measures 15kg/h at idle speed.
UPDATE: New maf completely changed the car.

More powerful, more happy to rev and better fuel economy. :thumbup::thumbup:

Maf now measures 20kg/H

Thanks David C for suggesting a tesdrive without maf :biglaugh:
