I am having problems with mk1 cabriolet golf -91 1.8 engine 2h. It loses power sometimes so much that going uphill is really stressing thing.
I am also a beginner so i dont really know much about these things. Is there a fuel filter located in this model where ? I was thinking that it might have some blockage.
Spar plugs look great and it sometimes runs okay also. And it doesnt matter is the engine cold or warm.
Thank you !

There should be a fuel filter somewhere as they are meant to be changed every 20,000 miles.

Plugged Muffler, Digi or Carbed, see it Vex me once on a carbed car I owned.
Vacuum Leaks
Timing is set wrong
Maf Sensor needs to be cleaned.
Restricted Air flow.
Weak Fuel pumps (is yours whining at the right wheel arch you can hear it over the Radio).
Bad Fuel Pressure Regulator (digifant).
Bad o2 sensor on digifant if equipped.
Bad CTS sensor on Digi.
Holed Air Intake Tube between the Maf and Throttlebody (digifant)
Is your Fuel tank partially full as in less than half, or is it topped off.
Just the short list off the top of my head this morning.

Then later today it feeled like it doesnt have the power and after turing right for another round the power suddenly came back ? It also drops rpm sometimes very low when i stop, but only for that moment. And also when cold starting sometimes the engine revs much more than usually.

If your grounds aren't brite and shiney you may want to use 2 off the shelf cables to replace them with.

You use the DVOM to check the hall sender going high to low.
Here is the link, it is the only way I use now.
Static Ignition Timing on VW A1 and A2 DigiFant Engines.
Used to use similar way on a old Beetle that my dad had, even my old 1148 MG and 948 Bug-eye we set with a lamp.

It's very rare to find a Digifant fuel injection system (I or II) in the U.K. Unless it's an import.
They are out there but not many as I understand.
They were sold in mainland Europe and the U.S, the D1 was only sold in California. My 1990 Cabby has the D2 and I'm in Austria.
So can you confirm which fuel injection system you have as to avoid any confusion please?
Because the problem feels like fuel and or air supply but I stand to be corrected on that.

he mentions code '2H' which is the euro digi 2 engine, plus the picture above showing the digi 2 blue ECT sensor confirms it
Fair enough John.
Hadn't realized the blue ECT sensor was only on the H2 wich denotes Digifant II.

I have found that the plastic flange that they are sitting in is prone to cracking at the mounting ears, caused by the radiator hose vibrating the heck out of the plastic bits due to engine vibration.
You can find a flange (metal) off of a earlier Cabriolet/Golf sans the extra hose connection on the bottom for the oil cooler, you will be happier. Just use a CTS sensor for a 16V, and a black oil temp sender (on earlier Cabbies over here they used the same sensor for 2 different things. Once you change it over it is one less plastic piece that will fail on you at the most inappropriate time IE: when your Baby daughter goes to a concert and is driving back home at 1:30am…and you get the call…….
Don't discount the comment I made about grounds needing to be replaced, and you didn't say that when it is having loss of power, you car hear a loud whine from the right rear wheel arch.
Also check for Vacuum leaks, I usually tell folks to replace all the cloth covered hoses on the thing.

oil sensors for VW are usually white, and different rating to the black coolant one
