Hello all, I hope that I can be helped here, so I have an Audi 80 Bj.88 1.8l 75hp (engine identification letter: RU), consumption approx.9-10l/100km and the problem that I have is when it is colder outside than approx.3°C and I start in the morning everything is still normal but after approx.15km when the engine is already warm it starts to take on less and less the gas.That means if you step on the gas a little bit more it will only swallow itself about 1-2 seconds until it fully takes it. then until he runs out at a traffic light at some point.After that he jumps up again immediately and drives as if nothing had been done.Has any idea what that could be.Bin very grateful for all the tips… the following I have already done: Benzium pump replaced fuel filters exchanged air filters in order relays and fuses in order pipes for the “gel” checked properly for false light (but only around the carburetor around)
