Hello good people.
I have a '90 coupe with M40B16 in it.
Bought it last year in November, after wishing for the past 10 years to own one. I dove in head first...which is the worst thing to do in any situation, let alone buying a 27 years old car.
Long story short, the car had some nasty plasma-type gauges which I threw out as soon as I got it. Installed a stock set that I bought second-hand from god knows how old-of-a-car (has 300.000+ km on the clock). Speedo doesn't work (neither did the one I threw out so I'm guessing it's the sensor leading from the diff). Gas gauge is not accurate at all, I have to rely on the warning light. Economy gauge is either max no matter what, or 0 when not touching the throttle. Rev counter works good from what I can tell.
My biggest concern is the temp gauge. When I put on the ignition, it snaps instantly to red without the engine running. I took the chance of driving it to work and back (1.5 hours of quite heavy traffic) and there's no sign of overheating. No weird smells, no excessive heat in the engine bay, no coolant leaks in the parking spot, heater works perfectly.
Important thing to mention: temp gauge worked fine after I've installed the new cluster. Drove it daily in Dec and Jan, staring out cold and slowly rising until reaching the center..and staying there as far as the engine ran.
What should I look for next? Sounds more like an electrical/gauge issue then anything else...
