I was sitting at a light last nite and my car just shut off and wouldn't restart. So i pushed it into a lot and disconnected my msd box and mannaged to get it started. But now i have a major problem. The ses light is now on and wont even re-set if i disconnect the battery. I can't get the ses light to flash for me to get the code when i jump the two ports in the DLC. It will not idle and it cuts the injectors off at 3k rpm.. it feels like the stock rev-limiter but that low.. And the way i know it is cutting injectors and not spark is my A/F guage fall off lean. it has an aftermarket chip in it, is there any way the chip has failed?
