Thanks for posting what difference that made. My plug wires were new at time
of swap, but lead from coil pack to dizzy  may be too close to temp sensor
wires causing an "intermittent short to ground". I replaced the wires from
sensor plug but didn't wrap with tape. Just a corrugated cover. The rest of
the harness is wrapped. Someone else here mentioned plug wires a while back,
but I wasn't clear on the "how/why".

For many thousands of KM's, I checked the engine bay every morning while in
camp. Glad I did. Caught these 2 potential issues:  (pics): coolant hose
shifted toward driveshaft (went over BIG bump)

wire rubbing on upper coolant hose: *http://tinyurl.com/2ejm7av*

My swap is not "standard" like yours hence my frequent inspections. Still,
I'd suggest that to anyone who's done a swap.

Neil.
