Hello guys, although I have struggled here through various topics I unfortunately could not find answers to my questions. So I drive a Legacy 3 Bj 2000 with the 2l machine and with a Prins VSI gas system. The car now has 122000 trouble-free kilometers down and has such a few problems lately. If it is cold it happens that the Subaru simply runs out after starting, so idling very unevenly and the speeds go against 0, then it goes out…start again… o drives again but the idle is always fighting with the die off at intersections. When it is then warm and switches to gas it runs as always. To this end, sometimes the engine control light goes on. The reading at Subaru revealed that the tap sensor reports an error and the exhaust system spins. The Subarumann meant that the elktronics “wrongly ” can come because gasoline and gas burn differently hot.. shone to me. What was not clear to me when I had a cost estimate. The Subarumann waved off and said “not needed”. Well my question: to my knowledge my Subaru does not have a hydrostottle that you do not have to adjust..or am I wrong? Should I have to adjust the valves…how can I do it myself? Ne small instruction would be very nice.
