All the little problems....
My Rex is begging for attention...
1.- The car runs a little hot...
It has two electrical cooling fans (10 inch pusher, 16 inch puller) and water wetter. This AZ heat is getting on my nerves. I think I need a new radiator. Is Fluidyne the best direct swap? It's also missing the bottom shroud (rock guard?).
2.- The wheel shakes at low speeds... I think my right front bearing is going out.
3.- When the car is hot, sometimes at startup the tach doesn't work. It will resume working after I have left the car off and it has cooled down. Why does this happen? Is it ECU related?
4.- My Redline buzzer doesn't work. Is this an ECU problem?
5.- The TPS 2 light check only works sometimes... Sometimes I only get one green light and it shuts off with some throttle, but then take a long time to turn back on. The TPS has been tested with an ohm-meter, and swapped with another one with no change. Could THIS be an ECU problem?
6.- When cold, it feels like one of my secondaries isn't firing. It goes away when it warms up. ECU? Ground?
7.- My horn doesn't work. ECU?
8.- When I pop my hatch, it stays closed but unlatched... New struts? What's that electrical looking device on the passenger side strut for?
9.- The little switch at the clutch pedal lost it's rubber pad so it clicks every time I push the pedal in... I tried glueing the rubber pad back on but it won't stayl... Can I remove the switch? Isn't it just for the "shift-up" light?
10.- Car hardly ever lets me downshift into second-- I have to RPM match and force the gear in for it to let me. I can't find MT-90 locally either.
If anyone has any advice on any of these problems, let me know. Maybe I will turn this into a "Small Problem Fix article."

Its a $1.25 part to fix and get a new rubber pad. The ECU uses the clutch switch for RPM issues, the Cruise control uses it as a shut down, and the starter interlock uses it to prevent starting in gear (except on 86 models)

The wheel shaking was a bubble in a tire... I put one of my spare wheels and tire on. But now I have mis-matched tires up front and the car pulls right. 
Icemark:
"It has nothing to do with the shift up light.
The ECU uses the clutch switch for RPM issues."
What RPM issues? I drive an '86, so the started switch doesn't apply, and I don't have cruise control.
Thanks for the link.
I plan to manufacure the lower shroud ouf of sheet metal-- I already did the same for a top shroud that was missing. I need to check out J-Rats Rex to see how the shroud is supposed to fit-- it's hard to guess.
I've done the TPS test, and I checked it with an ohm-meter. It was doing what it is supposed to do, and I still tried replacing it, but the same problems ocurred. It's not the TPS.
I've had hesitation before, but it dissapeared when I relocated my battery. My cold lack of power problem is definately not a hesitation- it occurs between 6 and 7k rpm.

7.- My horn doesn't work. ECU?
8.- When I pop my hatch, it stays closed but unlatched... New struts? What's that electrical looking device on the passenger side strut for?
And the thingy? Well, my '86 has a 'courtesy light' on the passenger side strut...
6.- When cold, it feels like one of my secondaries isn't firing. It goes away when it warms up. ECU? Ground?
10.- Car hardly ever lets me downshift into second-- I have to RPM match and force the gear in for it to let me. I can't find MT-90 locally either.

It has two electrical cooling fans (10 inch pusher, 16 inch puller) and water wetter. This AZ heat is getting on my nerves. I think I need a new radiator. Is Fluidyne the best direct swap? It's also missing the bottom shroud (rock guard?).

You should be using 50/50 for the mix or adding some major corrosion inhibitors.
The rotary engine being basicly aluminum will rot out very easy if the mixture does not have enough anti corrosion inhibitors in it. Most anti-freezes at 30/70 (30% anti-freeze/70% water) will allow the corrosion to start. I have seen a lot of water pumps and other parts fail early simply because the person was using a crappy anti-freeze or improper mix.
Furthermore even if you are street racing if the mixture is 50/50 you will have plenty of protection against overheating, if your coolent system is in good working order. Generally only if you or the previous owner have mucked it up by "weight reduction" or any of the other micky mouse removing panels ideas or missing/broken thermostats , will you have problems when using a good anti freeze with a 50/50 mix.

Probably for the lean burn on lift throttle, since the SA and to some degree the FB had problems with that, but I am guessing.

NO NO NO NO!!!!
I'll be leaving my mix as it is, then (50/50.) I was going to run it with more water for the summer, but I've kinda been talked out of it...
