Ground loops and 730 ECM

[Bob Valentine]

12 inches mabye, 18 I'd go heated.  I've never seen a stock 1 wire mounted
more than 3"-4" past the manifold outlet.   Mine is about 12" back from the
pass. side manifold.   At idle a single wire was fine but at highway speeds
it was cooling off enough to go open loop, and DMV response was very sluggish.

Heated 02's aren't just "preheat" it's constant heat.
