G37 feels like stalling when turning. Losing power.

Hey guys,

i have a really bad problem. I own an automatic Infiniti G37x 2013. Lately I been having a problem when I make a left or right turn, my car jerks and the rpm goes up and down. Feels like a manual going to stall but itís begging to push power. I took it to a dealer (Infiniti Of Bayside in NYC) and they checked everything and said it was the fuel pump being low pressure. So they changed that under bumper to bumper warranty I had and for extra backup. I cleaned the MAF sensors and the throttle bodies. I did the idle relearn and it was fine up to a week. Now yesterday as Iím driving the work. The car did the same thing to me as Iím turning however it wasnít as bad as before but you can still feel it. I havenít done any mods to my car other than new brakes and rotors, sound system (new amp and subwoofer), new OEM battery from the dealer.

Any help would be greatly appreciated.

Thanks,

Does this occur the entire time the steering wheel is turned or only while you're actually turning the steering wheel?

It happens randomly by the way. Forgot to mention that but when I turn the steering wheel and press on the gas a little bit. It starts doing that but when I turn the wheel straight, it doesnít do it anymore but it takes a couple of seconds to pick up speed. It doesnít happen every time I make a turn though.

Has this issue occurred before you installed the sub and amp?

No. It happened after I changed my brakes but I had dealer done them.

Why didn't you immediately return to the dealer?
Temporarily disconnect your amp and see if that makes a difference?
