Flashing light on my dash of a engine


hi patricia
FIAT engine light flashing means the ECU needs adaptation,
you can do it yourself just follow this procedure.
( remember not to accelerate unles is stated) start the engine
let it to warm and wait for the cooling fan to come ON then OFF 3 times, like ON,OFF,ON,OFF,ON,OFF. After the fan cuts off the third time accelerate fully down let the engine rev up to 4000 only then leave the accelerator let the engine goes down back to idle, do this 3 times.the engine light should go away.
good luck

While merging onto the highway when my car hit 3 and 4th gear the engine seemed to "stutter/misfire" during harder acceleration. Check engine light also flashed briefly during hard acceleration. Dur


Could be a transmission problem or something as simple as bad spark plugs.
The engine is under the most load when RPM is low and you are trying to accelerate, such as when it upshifts.
You should have the computer checked for trouble codes and hopefully that will point you in the right direction to test.
If the spark plugs have more than 50,000 miles of wear you might start with replacing them.

Stops accelerating and check engine light comes on


The check engine light indicates a fault in the engine management systems. Your car has stopped accelerating because it is locked in fail safe mode and normally you should be able to accelerate just enough to limp to the dealer where they wil scan the computer.
