Hi all.

Since my laptop code reader stopped working, I went old school and used OBD1
blink codes. I found ECT and VSS as before, but also IAC (idle air control)
and CMP (hall sensor on dizzy)  Whaaa?

Seems the related wires were too close to the ign. coil high tension lead
(Pic:  *http://tinyurl.com/3xse3mj  ) *allowing interference from high
voltage leads to leak into these wires. Repositioned wires, wrapped new ECT
wires with tape, no more codes.

Bonus: This may also cure the CEL intermittently lighting up, and brief idle
hunt when restarted hot. It may be that hot weather exacerbated the high
voltage leak.

Neil.
