Welcome to the group, there, Khal1d____ - :clap:

As @saltywetman asked:

* What is cursing (you or the engine) ? - ;)

* Is the engine throwing any codes? If so, what codes?

How many miles/kilometers on the spark plugs?

Have you had any previous problems with the coil packs?

Come back.

i ment cruising
no there no codes now, before i month it give fuel rail pressure low put nothing now. i have an air fuel ratio gauge it go rich then lean. i change the plugs in about 40K. and no problem with the coils

your car has a turbo? have you talked to your tuner to make sure that nothing with the tune needs to be adjusted?

do you have the datalogs?

Turboettes?

Mileage? Coil and spark plug age?
