I don't know when or how, but some jackass has confused my plug wires! I was under the hood investigating my vacuum hoses and I can see that one of my trailing plug wires is on a leading plug! I can see that the ciols say T1,T2, L1 and L2, but I am not sure how these correspond to the spark plugs. The trailing plugs are the ones towards the bottom; I know that much, but which plugs are L1 and T1? The plugs in the forward rotor, or the rear rotor? I would assume the front rotor, but I don't want to jump to any conclusions that will leave me with northing but a large rotary paperweight.

 

The bottom spark plugs are the leading plugs and the top or trailing.

L1 is the front rotor, bottom plug
L2 is the rear rotor bottom plug
T1 is the front rotor, top plug
T2 is the rear rotor top plug

 

Thats something that happens commonly if you make the mistake of taking your car to the dealership.
