I have been having problems with my '93 3000gt SL and keeping it running, sometimes it runs fine then others it idles low then cuts off, and help?
Lately, my 3000gt has been having problems staying running all of the time. At first I
thought that it was the ignition coils and replaced to set in the middle. After getting that
installed it still had problems running. For the most part my car would run fine but then the
idle would drop off to about 400RPM and wavier up and down before cutting off. After
trying to figure it out for hours and replacing the PTU with a new one as well. I figured out
that the wiring harness right above the ptu is what is causing the problem. I dont see any
visible damage to the harness but it seems like i can just wiggle the harness a little bit
before the car cuts off and the idle will go back to normal and the car will run fine.
anybody have any help please? i have to back at school this weekend and my car is the
only transportation there.
