i am at no way a tuner so please bear with me.
i have an issue with idle and cruising. i noticed on the laptop that if im at partial throtle on low rpm the injectors will go to 0% where it shouldnt ( told to me by a tuner ). it injectors just drop for a second. causing the car to just blimp. it wont stall but very annoying. he couldnt figure it out why it was doing this. also the idle will bounce every other time. so not every time i stop at a light. i was also told that if its a leak it will bounce everytime.

while just looking through the program i noticed that the injector size is set at 400 but my real inj size is at 500cc. would this cause my problem? i mentioned it to my tuner and he doesnt think it is the problem.

 

Check your fuel cut settings and see if you're within the threshold when the injectors cut. Change settings as necessary.

You won't necessarily bounce every time even if you have a leak. Check for leaks and adjust the IACV duty slider as needed to correct your ups and downs.

No, the tuner entered a lower value for the injectors so he started with a richer map.
