Hello everybody

I`m having another problem with my N55 f10 535ix, on the highway when i do and medium acceleraation not full power , in some gears at 2800 -2900 Rpm it cuts the acceleration for 1 second then it accelerates normal.

It happens everytime at 2800 -2900 Rpm and the most in the 5 gear like a limp mode with no error.

I had an error on the blow off valve and i replaced but the car do the same with no error.

What mods do you have on the car? Mileage and when did younlast change spark plugs if high mileage?

The car has Stage 1 software to 370hp and 83.000 miles . I buyed the car at 72.000 km and i didnt changed the spark plugs and i think the prevorious owner also didnt . This could be the problem?

Recommended change is 50k miles. I was having bunch of problems until I replaced sparkplugs. Could be a boost leak as well.

I forgot to mention... and now that I think of it, this issue could be related to throttle body/chargepipe.

My G35 did this and both throttlebodies were the issue.

i have changed the sparks and the throttle body today and its the same ,it stop the acceleration for 1-2 seconds at 2800-3000RPM in 4 or 5 gear ...please if can somebody help me because i have no error and i checked all the things.

Could this be from the gearbox?

Thats why I said to just do sparkplug only first :P. Check your intake filter make sure it is not dirty. It is like 5 screws I believe, so you can check your self. The intake filter should have been changed at 50k with oil change.
