Test fired up the car this morning after HG replacement, and it will start, then die, again and again. Something I noticed, while investigating the smoke in the engine bay, the cats are already HOT. The car hasn't ran for more that 10 seconds at a time yet. That scares me. Could I have the plugs wired wrong? Could that be it, thatthe spark plug is firing during the exhaust valve opening? Is there a way to test to see why it is dying? EEC-4 test maybe?
