Nissan skyline v36 G35
Help please! I am new to this, so desperately need some help. I have recently got a Nissan Skyline v36 350GT and it is having issues. Driving around town it is fine, cruising on the freeway is fine, however, once you exit the freeway and come back down to "normal speed" she splutters a bit and then continually shuts off every time you stop at lights. She starts up fine, but then dies as soon as you accelerate. You have to really "floor it" and hope for the best to keep her going. Any suggestions? Initially it had a 550v battery which was replaced by a 650v battery, which fixed the "around town cut outs", but then today it did it after being on the freeway and coming down to speed. It is booked in to go onto computers Monday week, but hoping someone here has had the same issue????? I was told to increase the idle rev's via computer?????
