1997, 230K, no mods to ignition system.
First time:
Just replaced cap, rotor, spark plugs. Re-used NAPA Belden brand spark plug wires from the previous owner.
New Cap: Bosch (made in Japan). The old and new caps (see below) all have identical markings and numbers, all same manufacture, different boxes when new.
New Rotor: Bosch (made in Japan)
Wires: Napa brand, Belden Max, used
Was running perfectly for 100 miles. Failed when towing trailer, 30mph, 1500 RPM - then instantly died. Pulled over, got the coil wire kinda back in and made it home:
Second Time:
Ran great for 400 miles, but it happened again today. 65 mph, fully loaded, towing trailer 5000 RPM, WOT passing an RV.
Since the first time this occurred I replaced:
Wires: NGK (Japan)
Cap: Duralast (Japan) Has identical numbering and markings as the Bosch, I assume same manufacturer, different box.
Rotor: Duralast (Japan) Has identical numbering and markings as the Bosch, I assume same manufacturer, different box.
So what am I missing? All the wires snap firmly into place and cannot be removed with a tug.
Anyone else have this occur or am I the only idiot? Toss the $hit cap and rotor and get Toyota? Toyota Wires?
And one more pic for fun:
