Engine Cuts Off When Hot Between Round 2000 Rpm

[Guest Peki]

Its been I while since I have been in "engine maintenance" topic.

Recently my gti ('91, 1.9 no cat.) started to cut off when very worm. And it happens in "city driveing" mode between 2 and 3000 rpms. I have no problem on highway. When I rev it , engine works normal, idleing is allmost perfect.

Nozzles are clean, fuel filter cca.8000 km old, spark plugs are 25000 km old.

Cables are 3.5 years old (46.000 km)

 

Any clues

You could try the ECU temperature sensor, this makes the engine run (very) rich when warm but is fine when cold.
