Coughing, backfiring ... *UPDATE*

The easiest way to do this is to remove the coil wire and then the #1 spark plug (front Drivers side) then using a helper to click the key over while you hold your finger over the spark plug hole at the #1 cylinder. You will feel the pressure push against your finger as the engine is being rolled around and "push" your finger out of the hole. At this point you can use a small screwdriver and insert it into the spark plug hole and you should feel the top of the piston just inside the hole. this will be very close to Top Dead Center on the compression stroke. Then, remove the distributor cap and take note of where the rotor is pointing in relation to where the spark plug wires are located on the cap as if the cap was clamped down. The rotor should be pointing at the wire that goes to the #1 spark plug. if it is not then the timing chain has probably jumped a tooth. be very careful when you click the engine over not to go past the top dead center on the compression stroke.
