I have to agree with Jim as well. There's not much I can't do in my
garage. I'm not the average car owner though having spent a decade working
on cars in the auto electronics industry. Yes, the electronics can be
scary but they really make routine fixes easier. I don't feel like the
fundamental parts of a car have changed that much in the past 30 years,
just the shear amount of technology stuffed into our cars is WAY more.

diagnose the problem. The chip that went bad in my 2003 was way under the
engine and he had to look around before he could find it... and my mechanic
is a genius at cars. Even he and his crew attend classes several times a
year to learn the latest techniques. So, I stand by my original
statement... the average guy cannot fix his car anymore.

I know that current designs are a masterpiece of continual trimming of
combustible mixtures and ignition timing and I am willing to concedethat a big reason
for the much improved engine longevity can be laid to this account, notto mention

carnage on the road, day and night unfortunately.people like me
I conclude that it takes an occasional pep-talk of this kind to get
beyond the sensor replacements (which are often misguided) and pointedat the plugs,
connectors, ground connections that are so often responsible forproblems these days.

Talking about plugs, it is just as well that ignition plugs last so long
just accessing them can be taxing.who

You simply can't diagnose a problem and repair the computer yourself.
outworked on cars in the 1960's are working on cars in the 2010's. Check
eachany car forum (e.g. www.neons.org/forums)--there are people helping
youother learn how to diagnose and repair (and soup up) their own modern
cars. Some out of necessity, some out of hobby interest.
You tell me I can't diagnose and repair the computer myself, and I tell
willthat the vast majority of the time I can do exactly that. Virtually all
failures come down to sensor or wiring problems. Tracking them down
requires the same skills needed to track down an intermittent spark or
headlamp, with a large dose of patience.
For less than $30 you can buy a bluetooth interface for your car that
andlet you datalog the sensor data from your car while driving. Reading
plugsinterpreting that data is analogous to reading and interpreting spark
to determine if you need to change carb jets.
I do however know a lot of people who believe the claim that no one can
work on cars these days. In the face of countless people doing exactly
that, I'm not really sure how to respond.
