Alfa cutting out - rpm sensor already changed
Hi. I have an Alfa 156 2.0 ts
Recently started cutting out when I reduce speed to stop. And this only occasionally. Also sometimes when I stop, it idles fine and then switches off. It usually starts again without waiting(so unlikely the crank sensor)
Whats interesting is that around the same time this problem started I've had my Heat gauge go to the red while doing 100km and go back almost immediately to half. Ive had my fuel gauge go to empty with the light on although I had over a quarter tank fuel. It went back up subsequently.
I have changed the rpm sensor about 6 months ago.
My mechanic tried a few things and now thinks its electrical but is no closer to finding the fault than he was 4 days ago.
