Hi folks. https://www.fiatforum.com/threads/hello-folks-newbie-grande-punto-driver.507660/#post-4740984
Here we go... Fiat Grande Punto, 1.2 and 68 hp. Bought it in 2011. Good little car, never let me down. I can do 700 km with 70 euros of gasoline.
But I presently have a host of issues when driving it on highways. I know, city cars are not build for highways - but no choice.
For a start, the dashboard varied lights are screwed up. (not my car - https://i.gyazo.com/ee759a1635bbbf0b239f21600b811bb9.jpg ) Start-and-stop, door locks: the lights no longer work correctly.
But there is much worse. The engine electronic controls seemingly have gone bonkers. When I accelerate past 110 kph on the highway, at some point the electronic somewhat "panic" and try "saving" the engine by dropping power and slowing down the car to 80 kph. Which is quite dangerous ! I've noted the phenomena happens on highways with declivity and ramps: the car just don't want to climb, at least not faster than 90-100. Also when the engine reach 4000 rpm.
Recently I've noticed that the start-and-stop light actually lit at this very moment ! No kidding - WDF, I don't know !!!
The two issues seems to be related, which is hardly surprising. Maybe the start-and-stop has screwed the engine parameters, one way or another.
I've found the OBD-2 and hired my stepbrother who is a gifted mechanics. He also live near a highway. Next weekend we will hit the highway and try pinning down the problem - and eventually reinitialize the parameters.
Do you think that's a reasonable move ? My older Punto (1996 - 2011) had the exact same FIRE 1.2 engine and never did that. Clearly the 2000's electronic control of the engine have gone crazy. The Fiat mechanics tried the OBD-2 but found nothing, which is not that surprising: the problem only happens pushing the car hard and fast, climbing on a highway. Not easy to pin down.
Anybody ever had such issues with a (Grande) Punto ? From memory, I think engine parameters and issues have numbers. Looking on the Internet I had found mine might be (from memory) in the P0300 series (301 to 304, I'll check again).
Cheers !
