Guys need some help i dunno why but yesterday around 2,500-4,000 rpms when driving and pressing the pedal hard i had a very strange acceleration behavior. THe car seemed like it was cuttting out or in general there was a problem accelerating causing the car to buck around like there was a problem accelerating.

The weird thing is that i had no engine failure or error lights when this was happening. Spark plugs arents that old about 10,000 klm, the fuel is from the same place i always get (unless if it happened to be tainted this one time).

I remember back in the day if it was a coil the engine would act like a tractor and the engine light will come on but its not. Any ideas? also i cleaned the injectors about 60,000 klm unless the gas is really **** lately.

is there a way through fes to see if a coil pack is at its last? i remember there was a way somehow.

No one knows how to check the coils on fes? the only thing i found was the voltage timing.

If its a coil it'll be misfiring and store a code.

so i took a couple readings using fiat ecu scan any chance anyone can help spot a problem since i have no experience in reading the graphs?
