My son needs to get the information on my 1990 Honda Civic LX 1.5L
Engine. The Schematics and testing information on the vehicle in
order to perform testing on my car. It pulls an 01 code on the
floorboard, and erratic idling. We have already replaced it once and
do realize that we could have had a bad one. We want to test other
sensors as well, but do not know what the guage should read. Where
would I find that information

important: code 1 and erratic idle are not necessarily connected.

re code 1, that means you need a new oxygen sensor. and not just any
old oxygen sensor, but either ngk or denso - bosch and other
aftermarkets don't react fast enough and you'll have endless problems
with them in a honda.

you're trying to do with it. fix the code first, then go back to the
idle.
is the idle erratic like it hunts up and down, or is it simply uneven?
if the former, check the coolant level, and for associated problems like
head gasket. if the latter, check the idle valve strainer is not
clogged, and replace the plugs/plug wires if they're old. make sure the
idle base speed and ignition timing are set correctly.
now, if that makes sense, and you check each of those items, you can
check out the factory workshop manuals here.

and of course, you can continue to ask questions here.

In article <40772b7b-8d61-49fa...@e42g2000yqa.googlegroups.com>,
I'd just get the manual from alldata.
