Secret Services recently installed adjustable cam gears, this was about 3 weeks ago.. They set the timing and all... seemed fine when it was at the shop, it hasn't been touched since. Since the new o2 sensor has been installed, the car doesn't backfire when i try to start it anymore, it almost starts and then everything shuts off, my friend is gonna come over and were gonna see if we can jump start the car... maybe from trying to start the car soo much the battery just doesn't have enough juice left.. I donno... I'm willing to try anything...
