Ok, so ive been having an issue with my GSX ever since i got the car dyno tuned about 6 months ago. The night it was tuned, i was driving on the highway and i blew my intercooler pipe off the turbo, which caused the car to buck and shut off obviously.

I fixed the pipe and went to start it and my battery was dead. So i was about to get a jump and then all of the sudden it came back on and the car started and ran fine. Now every few weeks it will out of nowhere just completely die at a stop light. No dash lights, no ignition clicking, just dead.

I get jumped and then have to keep giving it gas, otherwise it will die. Had battery and alternator tested and they tested good. The last time this happened i noticed something very strange, when i was about to jump it i hooked the jumper cables to JUST my battery and nothing else and suddenly the dash lights and fans kicked on. So i was thinking ok, i must have a bad connection at the battery and the jumper cables must have bumped it.

I changed both battery terminals and made super tight connections. Car starts right up and holds 14v. Then i went to drive it and here we go again. RPMs dipped very low when approaching a stop in neutral. When i go to shut the car off, usually the RPM needle drops slowly after being shut off from idle to 0. But now when i shut the car off the needle drops fast and hard, almost like it has a weight hanging on it.

The symptoms made me think i had a bad conection or loose wire but everything seems tight and good. Im at a loss and going crazy about this, any ideas?
