Hello everyone!
After digging out the forum as a non-member I couldn't really find the exact same issue I'm encountering with my Fiat Stilo 1.6, therefore I thought it was time to ask for help.
Here it goes..
A week or two ago I went out with my car and a friend to pick something up. As he went away I waited in the car while I let it run idle. After a minute or so I heard the famous beeps, followed by the ABS, loose connection and what not. Since it was the first time I've experienced this, I turned off the ignition and tried to start again. Which wasn't a problem. Didn't have any faults or what so ever.
A week later I was driving to work when "high coolant temperature" showed up, car held in on throttle, so I was forced to stop from going about 80 km/ph. After turning the ignition everything was alright.
On my way home I got the same fault, again the car did a hick-up, but I could still drive my way home.
1. Immediately went to a friend of my dad, who owns a one-man-garage where he is almost retiring from. Connected the OBD which didn't really gave an error except for a U1601 mobility-something. It did tell me there were faults in the temperature gage, but I thought that was just because it's reading went out.
We tested the car battery, which matched the values of the highest battery available, I believe it was 14,4 idle with 490Amps starting power.
2. Since then I've checked the groundings, disconnected every piece of electronics I've built in (amp, camera, lcd-monitor). I also changed out the LED's I'd placed in the headlights, as I thought they might've messed with the CAN-bus. I've checked the ECU in the engine compartment cause of the possible overheating problems, and replaced it with a bracket next to the car battery. Nothing seemed off.
3. The day after I was driving to work when something different happened. The speedometer dropped to zero, engine light on, car loses throttle, and all in a second. After that second it seems nothing has happened, no faults on display, nothing. I decided to take another car to work, as I really can't be stalled in the middle of the road, as my journey to work contains a few tunnels.
4. Today I decided to check some other connectors, especially the D4. Again nothing seemed off. I went for a drive, after about 10 minutes the speedometer dropped to zero, same thing as before (3). Which happened twice during that 25 minute test-run. Back home I've let the car run stationary, nothing happned. As soon as I opened the door the engine stalled, don't know if it were a coincidence.
Checked the wiring loom that goes to the drivers-door, nothing seemed wrong.
5. This evening I decided to go on another test-drive. Again after a few miles speedo dropped and throttle 'dipped' for a second (3 and 4).
A few miles further I got the 'high coolant temperature' fault, 'stop engine'.
The reason I started a thread was the fact nobody seems to have the exact same problem, where the speedometer drops for a second, along side with throttle 'hick-up'. I was wondering if there's a hero out there who can give me a few tips, along side with a bucket of hope.
Thanks in advance.
