And what about the availability of these electronic pieces in about a year or ten? Go figure out:snorkel:
The engine and most of the electronics in my old (1985) jeep are from 1997; I had an XJ (Jeep Cherokee) from 1991 with virtually the same engine last year and there was no problem getting any sensor or electronic part; that's here in the US though.
Questionable parts availability (above and beyond the essential spares that I carry) is one reason that I would have to spend more than a bit of thought (and possibly carry some stone age spares) if I were going to travel the third (or even second) world with this vehicle.
Although many modern engines no longer have provision for a distributor, my current engine (Jeep 4.0 liter) would run without the electronic controls if I install an older distributor, a carburetor with adaptor, an ignition resistor and drop the high pressure fuel pump out of the line (I have 2 fuel pumps a low pressure supply pump at the tank and a high pressure injection pump near the engine, I found that this eliminates any tendency, for this particular engine, to vapor lock in the desert heat).
For a long time I, too, was leery about electronically controlled engines, and this was justified with electronic carburetors, but electronically controlled multipoint fuel injected engines have shown themselves to be (in my opinion) probably the best thing to happen to vehicles since electric starters and electronic ignition...
While I am a fan of fuel injection everyone should run what they are comfortable with.
Enjoy!
