Given the limited capability of the 1987 EECIV system, all
you need is a cheap code reader.
It's not a question of tool adaquacy, it's the vehicle
system that presents the limitations. i.e., the 1987 EEC IV
system is limited in its capability.
A paperclip would be adaquate, the Walmart cheapy

A real scan tool costs $4000+
It would also not do much more than what the $27 walmart
piece does (on this particular vehicle).
Twenty seven bucks is lunch money.
You might find something cheaper on e-bay or online vendors.
Thanks, again. I might just go and try the Wal-Mart product, just for the heck
of it, then. I saw on the package that this reader give the codes for many
vehicles, including Chev, Ford, Dodge, etc.. It's a cheapy, but if it doesn't
work, it does come with a warranty.
if you talking about the trouble code reader the ones i saw for the pre
1996 model cars cost about $25.00 and dont do much but the light flashes
or makes a beep... the code readers for the 1996 and later cars can cost
about $150 for a low tech one to $650 for an improved one..............
the pre 1996 cars use the cheap one and i have not seen anyplace where
they sold them for more than the price that you mentioned.... some might
come in a facy box and have a manual, but they dont tell you much...
example: you cannot put the code reader on and find that you have code
123 and you look in the book and the book tells you:
go fix the blank, blank, blank.... it will guide you into what are of
teh car to check, but you still have to figure out what is wrong with
the system and it might be one of several things wrong with the car
system and you still have to trouble shoot it down and fix the
Use your $27 to buy a decent manual.
Look at this site:
It will tell you how to retrieve the codes with a paper clip, list them for
you, and add some decent explanation to the whole thing too. I have never
seen the brochure which comes with those commercial $25 code-readers, but I
suspect that it's not anywhere as good as what you will find on this site.
The guy who runs this site pushes his own book (that's the main purpose for
the site), but I have enough books already and didn't need it, so I would't
be able to tell you if it's any good. If it's as good as what he posted, it
may be worth the money.
