Hello everybody,
First of all, thank you for taking the time to read this post. It's my first post, I have no idea how everything here works so I'm open to suggestions from all of you.
I have a 2002 Fiat style 3 door with a 1200cc petrol engine that has been converted to LPG. This conversion was done about 2 years ago.
About 1 year ago the car started to misfire in the cold weather. It was difficult to start and the idle was unstable while the car was not warmed up. If I tried to drive the car before it was warm, it wouldn't have the strength to go. The RPM would just go down and I needed to put the throttle way down and almost rev the engine form it to be able to move.
At first this only happened on cold days but after a while it started to happen all the time. It was not starting for the first 3 to 4 key turns and them when finally started the issue as the mentioned above.
My father is a mechanic and has been trying to help me with this problem. At first we thought it might be the conversion to LPG. We disabled the whole system and the car was fine for a while. We turned the system back on but it was still fine. A few more weeks passed and the problem returned. In the meantime we have already changed the spark plugs 2 times, we have changed the crankshaft sensor but nothing worked. Twice the fuel pump failed. We thought that might be it. It has already had two new ones and the car is fine for a while but then the problem returns.
However, the last attempt we made was to replace the car's ECU. This was 4 months ago. The car was fine, even on very cold days there was no problem. We thought it was finally resolved. However yesterday the car started again with the same symptoms.
We don't know what else to try.
Have any of you had this problem or have any suggestions of what might be happening?
Thank you all! Have a good day.
