Hi everybody! I would like to ask a little help if there is someone in the group who has encountered such things and could help. He gave me a Lancia Thema 8.32. The car was long for years and has just been launched. The old fuel was removed from the fuel tank and fresh gas was added. New fuel filters, fuel distributors and injectors were cleaned and checked. Timing belts switched, accurately set. After all this, the engine started, went well, oil pressure was OK. BUT! After starting, the idle travels around 1000-1200, but as it warms up (about 85 degres in about 5 minutes), the idling rises to around 1500-1700 and stays stable there. Apparently the sensors are good. I thought about vacuum tubes or somehow falsified, but so far I have not found any signs of sealing, and maybe if it is wrong, then it would be cold at the idle, not just hot. I am looking forward to the ideas and tips I would like to thank in advance!
