Hello, now that I have searched the entire forum for solutions, I have come to the decision to write here about my problems and to ask for your help. Now the problem: The Fiat Uno, bj. 1990, 1.0 Type 146 with G-Kat does such a thing from Mucken, which is simply not true anymore, he just ran until then and suddenly he went out during the ride, took no more gas, starts even under wild pumping with the gas pedal, remains also, if ma n holding with the gas foot at moode, but has no performance ……… Well, we thought, is not a problem, have still disassembled a second building equal in parts, is all there ……. said: carburetor out, others in (we made 3x ) }}} nix, still the same distributor out, others in }}} nix, still the same new petrol filter ( petrol is pumped at start ) }}} nix, still the same lamda probe changed }}} nix, still d }}} nix, still changing the same engine control unit (we have 4 pieces of it ) }}} nix, still controlling the same timing timing belts }}} all correct The funny thing is, WHEN it happens, then it’s really round, all cylinders are there, he’s not jerking, just clean ……. but he just tortures himself as if he didn’t know what to do with the gasoline, what to give him, even remains in a warm state. I hope my text is not too long for you, please give me a little bit more input, are grateful in every way about inscriptions, because the little one is urgently needed and coal for what is new is not there, even if our state has so crazy offers on it ( scrapping premium ). Thank you your Volker.
