Hi,
I have cutting out issue on 1.6 2002 3d Stilo. It happens during idle and on the move even when it is on gear. It cuts out during driving, no response for 2 seconds from the car and then starts working without me restarting with the key. Sometimes it needs restarting with the key.
It does the issue:
- On petrol and on LPG
- Cold and Warm engine
- Raining and sunny weather
There is no pattern in my opinion.
Errors on the dashboard:
- Combination of: ASR Failure, Alternator Failure, Loose Connection
or
- combination of: Engine Failure, Loose connection
- once it was Security failure
in general random errors.
I started with all the topics with loose connection in the forum i could find as well as guides:
-Cleaned the D4 connector
-Changed the crankshaft sensor
-Changed the coils
-Measured the accumulator - 12.6V with car not running; 14.4V with running engine
-started to go through the earth points- the only one left is the engine one i couldn't reach today because the point below caught my attention:
The ECU connectors the "A connector" referring to the guide: https://www.fiatforum.com/stilo-guides/338370-1-6-ecu-pinouts.html#content_start
the insulation seemed a bit worn out.
So i started checking the loom and dissembling the connector when I saw that there is something strange ( check the first attachment). In my opinion the previous owner has done some modifications in the connectors.
1) Blue wire connects to Blue with black i guess there is a resistance in the black joint and then goes in pin 13 of the A connector.
2) White wire connects to Black with yellowish wire again i guess through resistance and goes in pin 7 of the A connector.
Is there something like this in someone else's 1.6 Stilo?
How come something could be connected to pin 13, where the guide says it is not connected to anything
I counted twice the positioning of the pins from both directions so i am almost sure it is the correct pin number.
Could this be the reason for cutting out after i have driven the car for 2 years now ?
Initially it had troubles starting but they disappeared by themselves and it was OK for 2 years.
I am totally confused how to proceed.:bang:
