Roll the red die when your engine won't start
It could be a problem with your timing belt, battery, fuel pump or relay, ignition module or your crank/cam angle sensor. Roll the die and check out what comes up *  what have you got to lose?

Roll the orange die when your engine idles roughly
It may be a vacuum leak, something wrong with the injector valves, spark plugs, the ignition coil, plug wires or the distributor cap.  Take a look * it may lead to a solution

Roll the blue die when the engine is overheating
Could be you need a new head gasket or as simple as a busted thermostat? It may also be something wrong with the temperature sensor or gauge, the water pump, a faulty radiator or an improperly seated or leaky radiator cap.  It could save you from a seized engine!

Roll the yellow die when you have no power
Is the ignition coil damaged, or it could be low fuel pressure? It could also be the mass/map sensor, the transmission, knock sensor or even restricted exhaust.  One of these could be exactly what your problem is!

Roll the green die when you're reluctantly facing the worst case scenario
Bite the bullet and roll. Do you need a new engine? Is your catalytic converter shot? Possibly it's your wiring harness, a new head gasket, a new transmission or control unit.  Any of these could be the culprit.
