Hello. I am from Sweden and own a VW Vento 1997 ADZ.
I hope that it will work fine that I write in english. You can write in German if you want. I can use googletranslate.

The engine is power less. The car is very slow.

0-100 goes in like 22 seconds.
Should go in 12,7 according to this?

When you hit like 120 - 125 km/h the car wont go any faster.

Checked things:
* Timing belt is correct
* Ignition is right. Both on oil pump gear and in live data on the computer connected on to the car.
* No air leaks or bad vaccum hoses.
* All service parts are changed. Fuel filter. Air filter. Sparkplugs. Ignition parts.
* No error codes on computer
* Engine coolant temperature sensor changed
* Fuel delivery is OK. About 1,5L/60sec.
* Catalytic converter checked. See pictures.
* Central injection checked with resistance with Autodata reference.
* "Upper" part of fuel injection changed.
* Central injection flange/gasket on intake changed. https://www.mekonomen.se/systemmedia...gasarflans.jpg

Spark plugs are white. Running lean?

Catalytic konverter:

0-100 Km/h with the catalytic converter deleted. Slow start on studded winter tyres:

100% throttle all the time.

Any more suggestions? Running out of ideas.

Thank you!
