93 LT1 6-Speed Quits When Hot
My 93 LT1 vert (137K miles) started acting up a while back. First symptom was immediate engine cut out with the tach dropping to zero and the ASR light coming on. In the beginning it would quit for a second or so and then run again. Over the next couple weeks it got to the point that as soon as the engine got up to operating temp (about 180 degrees) the engine quits. When the engine quits it's an immediate cut off so I suspect elctrical or ignition. It will restart after having a chance to cool and run until it heats up again. I've already replaced the Ignition Control Module (ICM) and the Opti. Any suggestions out there on where to look next?
