Never had problems (with -12 degrees in winter) starting my '97 147 1.4TI, until this afternoon. I had to keep the starting motor running for 20 seconds to get the engine running. The only reason that I can think of is that I washed my car this morning, so maybe the spark plug cables got wet? Is this possible?
As far as I can think of the CODE-key light was off during starting the engine.
It happened again. I don't think that it's the battery, because when I started it this afternoon (I already started it in the morning, again only after 15 sec or so), the engine started immediatelly, but for a few seconds it had some trouble getting above 1000 revs. When it did, the engine ran ok. Where should I start looking for the cause??
When I refueled the car today I heard a strong sissing sound when opening the tank-cap. Could it be possible that the pressure in the tank is not right, causing the engine to run lean on fuel?? Does this sounds familiar??
try a reset of the ECU, disconnect battery for a few minutes (put the + and - together for a second) and reconnect the cables. Maybe a 'relearn' of the ECU solves the problem.
But I think that you have a lamba sensor problem.
