91 honda accord has a few problems...

first off, the S light flashes all the time. The check engine light comes
on after driving it for a little while and lastly... when you turn the car
on it seems to putter (or at least thats what it sounds like) it takes off
fine, but you can feel it "putter" when driving and when stopped at a
light... any ideas?????

 

Count the blinks. The sequence is separated by a long pause. If there
appears to be just a steady constant blink, it's code 1.

A long blink is worth 10, a short blink is worth 1, so the sequence
long-short <repeat> = code eleven.
short-short-short <repeat> = code three.

Pull the carpet back in the passenger footwell. There is a small LED set
into the yellow framework you see there. Turn the ignition on (but not
START!), and count the blinks.

Blink sequence is as above. There may be more than one code stored, so
watch carefully.

Need those codes first.

 

Does a '91 Accord actually have a LED there? My '93 Accord, which is the
same generation, does not have it and must have its codes retrieved from the
check engine light with the service check connector shorted.

 

My 90 has an LED.

 

According to my Helm manual, yes.

 

And Frank B. said his '90 has it. I guess Honda removed it for '92 or '93.
I know it's not the best source, but my Chilton book only mentions the
service connector method for retrieving codes on the '90-'95.

 

I bought a Honda service manual when my 90 went off warranty. Ugh,
very expensive compared to Haynes, Helms, Chilton, etc. However, best
manual I've ever used with regard to chronological trouble shooting.
I have a Haynes for my 97, however, I always go to the 90 manual first
to see if it applies.

Have you actually looked? Book may be wrong.

Yeah, I looked a few years ago, and there was no LED.

I don't use the Chilton book religiously. In fact, it was a birthday
present.

 

www.autozone.com 's free repair guide for the 1991 Accord states:

"On 1990-95 Accord (except V-6) and 1992-95 Prelude, the codes are read from
the check engine light after the two-wire service connector has been
jumpered. On Accords, the service connector is under the dash on the
passenger side."

(The autozone site tends to be a replication of Chilton's, though. Still, I
haven't found any notable errors in Chilton's for my 1991 Civic. The
autozone site says 91 Civics have an LED display, and my 91 Civic does.)
