It's a strange issue, it started with unstable RPM, which happened once in a few days and it didn't matter whether it was a cold start or not. It would rev up and slowly go down at idle, or it would just rev up and idle at over 1000.
When I'd change gears and release the gas pedal it felt like it revs up a bit. And if I held the clutch down the RPMs would stay up there and only go back to rev up and down again only after a few seconds.
This occurred both on cold starts and when it warmed up and went on for miles. After switching it off and starting it a couple of hours later, suddenly everything went back to normal.
I was at the garage on thursday, they hooked up to the ECU to check for faults, and found none. The Lambda values were good and everything looked "ok". So they told me to come back again when this was happening real time.
But Friday I went to the gas station, had it switched off for a minute (before filling up), started it up and it would just smoothly cut out, RPMs would just drop to 0. After filling up, same thing. But once in a dozen attempts it would hold idle and not stall.
Not sure how accurate this is, but as long as I start it cold and don't switch it off it seems to hold idle even when warm. But if I switch it off and try to start it up again it will cut out again and again.
First thought of the garage was a dirty ICV, but they took it out and it looked OK. It was a B1300 (I think) Magneti Marelli (made in USA). Since a new one at the garage was $190 + labor and they couldn't guarantee that it's going to sort this problem out for good I decided to try and see if there was a chance of it being something else.
So I heard of the PAS sensor issue, and I thought that it was possible that it was the reason since I had the hose refurbed not too long ago and maybe it was damaged or something, but I don't know... I'll see if I can get it unplugged tomorrow at daylight.
