Hi Fiat experts,
I have been having issue with my 2006 1.2 Grande Punto (60, 251 miles)
It has been going for a month and been scratching my head over this issue. :bang:
It started with the car had a rough idle with the rpm meter jumping up and down around 1500 - 2000 rpm. The car then started to stall at the junction once the clutch is down or braking ,i.e. at low speed/rpm. The car won't start when turning the key normally. It will only start with pressing the accelerator pedal down while turning the key.
The next day, went to the local garage to get it checked. The mechanics:
- ran diagnostic
- cleaned the idle control valve
- changed the camshaft sensor
The fix improved the rpm meter jumping for a day and car started from cold normally. On the way home from work, the car stalled at the junction again. Had to wait for a while to restart the car and only started when pressing the accelerator pedal.
The next day the car won't cold start without pressing the accelerator pedal down while turning the key. Once started, the car ran nominally until the engine is hot around the middle temperature mark and the car stalled at stationary, see attached image. It is similar to someone turning off the engine. The car also stalled at junction when braking or clutch is down at low ~ 500 rpm. Rpm meter did not jump up and down anymore.
Second trip to the mechanics:
- Changed knock sensor since the reading was jumping up and down.
- Changed spark plugs
- Cleaned throttle body
- Tried a brand new throttle body, but that did not improve the issue, returned the part to the supplier
After a week of looking at the car, the mechanic could not fix the fault and suggest a different mechanic with more electric/ECU experience.
Current issue:
- Doesnt cold start without pressing the accelerator down
- Stall at stationary when the engine is hot around the middle temperature mark.
- Stall at junctions at low rpm when the clutch is down or braking
No fault code error and no warning lights appear on the dashboard either.
Been looking around for similar threads, it seems to be a crankshaft issue with similar-ish symptom.
Recent car history:
- Cambelt, water pump kit and temperature sensor changed 3 months before this issue.
Going over to the other mechanic in the next few days. Hoping that maybe one of you had a similar issue and could shine a light to this problem.
