Linea Please Help Mil Light at high rpms

[Kelhamla]

Hi guys. I'm new to the forum and I have been facing issues with my 2014 linea 1.4 fire. Car goes into into limp mode at high rpms and engine starts to stall. It limits the rev to 4000rpm and when I stop the car and start again problem is solved but it continues at high rpms. Engine limits the revs. How can I fix this issue?

Read fault codes using code reader.
Though could be cylinder/s misfire.
When was it last serviced? How many miles since spark plugs changed?
How many miles had car covered?

Fault Codes p301 302 misfire and i changed the spark plugs 2 times but no luck. The car works fine but if it reaches high rpms it start loose power and limit itself to 4000 rpm.

It has 170000 kms on it.

If engine ecu detects missfire it is meant to enter limp mode to protect car from damage.

Have you changed the ht leads and coil pack/s?

Did you put new spark plugs in or used spark plugs?

What brand of spark plug have you fitted?
Are they the correct part number for your engine?

 

[Kelhamla]

Yes i changed them

 

[Kelhamla]

Marelli spark plugs and before that it was ngk

Change spark plug leads and coil pack/s.
170,000 km is not a lot if engine has been cared for -serviced regularly

 

[Kelhamla]

I changed all spark plugs, spark cables, and the coil i am thinking ot may be a phonic wheel or self adaptation or bad timing belt
