Finally got to have a crack at replacing the thermostat today. Took me awhile to figure out the best way to get at it with a few bashed knuckles and all along the way, but finally I was able to get at it, and get the new one installed.
Then I took the dizzy apart. Discovered it has been taken apart before, so it's either a replacement or the original. I couldn't find the bolts to the ICM itself as the guide on here isn't quite what I have on my car. So onto plan B which was to take the connectors off, spray contact cleaner in them and check the connections were solid. It was at this point I found one that was kinda of loose, so I closed it to make a tighter connection. Also sprayed some throttle body cleaner into the throttle body.
Then time to fire up the car, and it purred. Yay. The temp gauge is now working properly, and the tacho isn't jumping around at all. Car even zooms better too, and it feels more responsive. Just to be sure I took it for a good drive on the freeway and the temp gauge didn't go down with time, and the tacho was rock solid. So mission complete on those areas.
Now to see if I can sort out the antenna not extending when I turn on the radio. Hopefully it's just an issue of the wire not being connected.
As for how the gear changes from 1 to 2 go, it's alot better. But I think the clutch pedal might be setup so it engages immediately. Will peer under the dash and see if there is an adjustment thing to back it off a tad.
