General problems, like the radiator went out, and all the belts were worn out.
The A/C broke.
Rust is a problem, and it leaks a little oil.
This truck still runs good, has plenty of power for a 4-cylinder, the cab is roomier than many new small trucks, and the gas milage is decent (mid twenties).
You must have gotten a good one, because mine was a piece of junk!
I can't complain about my 1990 b2600i mazda the little truck is really good all around. normal wear and tear ball joints, exhaust, tie rods.
It leaked oil when I first got it, and I noticed all it was the oil plug was loose.
Most all problems if undetectable are the stupid ECU. They have a 100 percent failure rate. You have to get the leaking capacitor fixed by a specialist. The leaking fluid causes all sorts of problems as the capacitor (or whatever it is called) leaks all over your ECU circuit board behind the passenger kick panel. The capacitor still will function but the liquid that leaks on the circuit board causes all of other problems. Depending on how and where it leaks.. ALL of them will do it someday!!!
