I can smell the answer 150 miles away, but here in CA, is it not illegal to retrofit a heated o2 sensor onto these motors, since they never shipped with a heated one from the factory?
The mantra here is "certified configuration" I know, and the heated o2 sensor won't be 100% the same (as an o2 sensor, leaving aside the heater). But this is one emissions shortcoming these motors have, the o2 sensor drops out of temp quickly the moment you turn the key off, and you have to gun the thing for a couple minutes to get back into closed loop. So it would be an improvement -- and illegal in CA.
Am I right, gofstbuick?
