my opti is failing, which doesn't suprise me at all.

today i gave it some gas in a merge lane, and it broke up at 3k. the check engine light came on, set a code 36, and it ran fairly normally the rest of the way home. (i was limping it of course)

my question is, once code 36 is stored in an OBD-I LT1, does that mean that it's running off low res pulse only?

obviously i'm going to replace it, it's just a curiosity thing.

oh of course, but i know it's not going to be the harness. mine has a broken retainer, so i checked resistance, then i epoxied that sucker in place and coated it in neoprene a few weeks ago.. knowing that if the opti ever failed, its time for a new harness too.

this opti is broken somewhere too; if you attempt to pull vacuum from the vac hose, it draws air from somewhere other than the vent line (meaning the cap is cracked, seal is screwed, or something..)

i betcha its been sucking in unfiltered crud from the engine bay for a while.
