Limp Mode on Initial Start-up
I recently came back to 156 ownership with a 51 plate 1.8TS picked up very cheaply to cover me for a few weeks. How could I have forgotten how infectious they are...
Anyway, it was running very roughly until it started to heat up - no power when you put your foot down. MAF has been changed for a new Bosch one only a few months ago.
I took it to a local Indy to have the fault codes read (injector light showing all the time) and they came back with two coils (definitely melted when I bothered to look closely!) and the rearmost lambda sensor as being the only major problems.
Swapped the coils for a set I had kept from my last 156 and fitted a new (but pattern) Lambda.
Did the full ECU reset procedure and then the throttle reset.
Took the car for a blast and all was great. Performance was up, revved sweatly, job's a good 'un I thought. Came home, tidied up, left to collect the kids from school and it went straight to limp mode.
Switched off, switched back on and no further problems.
Since then I've had occasional lack of power - not nearly as bad as when I got it but still needing plenty of revs to ensure a smooth take-off - and the fuel consumption seems to be getting worse too. An ECU reset cures these symptoms for a day or two.
It's also now sounding like the variator might be on its way out and I seem to sometimes get a clicking noise under load - I think anyway, can't reproduce this noise at rest or at least can't hear it under the bonnet when somebody else revs the car.
Yesterday I started getting limp mode as soon as I start the car, but switch it off and turn it straight back on again and I have no further problems! It seems if anything to be running better than it has been once started for the second time!
Anyway, I'm guessing at a sensor somewhere being out. I'd like to get it running properly again, so any ideas?
The car's really still only a stop-gap so I don't want to be spending hundreds at the (very helpful) local Alfa specialist.
