156 shuddering, cutting out in 4th gear. no power
Hi there and thank you for accepting me into your forums. Owning an Alfa for nearly a year now, I can say it has given me more pleasure than any car I've yet owned.
Nonetheless I have a problem that I hope someone can shed some light on.
Recently, when coming off a motorway onto a traffic laden street, my alfa has been acting up. When I'm in, say 5th gear and brake, instead of rapidly de-cellerating back to 3rd, the car seems to trip at 4th gear and rev erradically. At this point when I give it gas, I have absolutely no power and have only the option of turning the engine off.
The fuel injection warning light comes on.
I can immediately restart the engine and drive away, the light turning off after about 30 seconds.
This has happened a few times in basically the same circumstances.
An exception to this was tonight when I left work (quite cold out) and the car stalled after about 4 mins of driving at low speed. Again, immediately restarted with no issues and got home.
Looking around the forums and seeing similar issues, some have told the others it may be a crank sensor or lambda sensor.
The car is overdue for a new timing belt as per recommended service, but I doubt this is the cause of the trouble.
Thank you for taking the time to read this, perhaps you can help identify the problem.
My technical details are:
2000 Alfa Romeo 2l Selespeed.
160k on the clock
All levels are fine (coolant, oil etc)
