What do you think about the big "avoid electronic" push?
Are electronics good? Yes and no.
I've been working on and earning a living working on cars for over 50 years. When I started, unless the engine was physically broke, it wasn't all that hard to get it running with a few inexpensive parts. A service call often just involved adjusting the points, you could "eyeball" it, checking the choke for operation and putting in every other spark plug in firing order. Pretty much everything was able to be taken apart and fixed. A tune up was 10,000 miles or once a year.
First on the scene was electronic ignition, I always worked in independent shops, we didn't have the "factory" test equipment, nor did we have a spare module sitting on the shelf to plug in to see if that fixed the problem. The modules were expensive and unreliable. Many people carried a "spare" module with them. If we did buy something and it didn't fix the problem, it came back off. The factory dealer wouldn't take it back because it was "used", the customer was NOT charged for a part he didn't need.
Next were the many forms of fuel injection, which in my opinion were a huge leap forward. They were kind of "electronic" but relied mostly on air flow and temperature sensors. There wasn't an ECU for the whole engine.Things were getting harder to diagnose, service manuals were hard to get and expensive. Test equipment pretty much was a fuel pressure gauge and a VOM. There was no internet or hot line to call. The parts, though, were getting more and more expensive and less and less repairable.
By this time we had pretty much quit going out on service calls. If it didn't start we called a wrecker.
Todays engines, both gas and diesel, for the most part, last longer, get better mileage, have more horsepower, and are more reliable. When I started out, an engine with 100,000 miles was pretty rare. When everything works right, and for the most part it does, everything is wonderful. When something goes wrong, even the most sophisticated test equipment can't find all that much. It can tell you the general area to look. A good mechanic uses that info to start testing, but there is still a lot of testing that needs to be done, and that gets expensive.
Independent shops are getting pretty rare, just because the cost of information and equipment is too expensive. There are also less and less dealers around. My little town used to have three GM,two Ford and a Dodge dealer. Now, there is just one GM.
I work on my own vehicles, they are both mechanical diesels. My wife has a late model SUV with all the buttons. I fix the mechanical stuff, if and when the electronics go bad we'll probably just buy a different car.
