Old Miata never dies (short film, 1992 NA6 with 37x,xxx miles on )

[S21FOLGORE]

Recently, my NA6 became 3 cylinder in a 100 degree heat.
(I normally don't drive in the middle of the day.)
Then, it started beeping horn without me pressing horn button.
(The car has tendency to do random interesting things when it gets really hot.)

I made up quick video out from dash cam footage and some clips I shot while working on the car.

Yes, it's still running on original head gasket.


Being 28 years old car, with over 370,000 miles on it, it has no value as a vehicle.

It has been vandalized a few times and the damage is visible.


Every year CARB sends me a letter suggesting to scrap this car (and they would give me $1K for that).

It's small, all black, and lowered, doesn't have the safety features like today's car.

No, I don't keep driving this because of sentimental reason.

Wow, AFM... haven't seen one of those in while!
Miatas are so much fun!

So when do we get a build thread for the LS swap?

 

[GAJ]

Just spent some decent money after 10 years of just oil changes on my 1994r I bought new.

New Fat Cat Motorsports suspension, deferred maintenance including a new head gasket, tires (195/50-15 Dunlops), Delrin door bushings that eliminated all the door rattle and shifter rebuild kit that eliminated the heat pouring up out of the shift tower and restored the shifting action to "like new."

188k miles so still breaking it in compared to your car.

Just replacing spark plugs and spark plugs wires didn't completely cure the problem.


It still does the same thing (running on only 3 cylinders) if I re-start within 15 minutes or so.

(If I let it sit for more than 30 minutes, it would start and runs perfectly fine.)


So, today I checked the primary and secondary resistance of the coil pack.


They appeared to be okay (within spec), but there's still possibility of coil pack having intermittent problem.


The story continues.


BTW, the opening sequence was shot with vintage (1976 or 77) Nikon 50mm f1.4 lens. (Also, first part of the multi-meter work scene.)
