With my Saab 9-5 2.0t Prins LPG, the cold start has been a bit difficult for some time now. It’s supposed to be 6-7 times until it starts. So far, I assumed that after a Prins SW update it would inject a little bit more gas after it was parked and issued. This gas leads to it being too fat and turning longer when it starts cold. Now it’s the case that I changed the battery two weeks ago – this lasted about two weeks. After that 600 KM of motorway and highway drove and once again about 50 KM through the city. I noticed since change that he occasionally takes a bit of bad gas after starting. If he switched to LPG it was no problem any more. Yesterday he just went out shortly after switching off at the traffic lights. I set the gas system a quarter of a year ago by a real professional. .. so I don’t know any more. At that time the car pulled false air and went out constantly .. in the error memory was nothing. My question now, can still have to do with the learning phase of the ECU – or is that after 650 KM already sufficiently set. And what are the reasons that the car simply runs out.
