Re: the old PGM-FI thing - i have 87 honda prelude
That document is where I was looking before (although a different
link). My car is a *1987 Honda Prelude* which is the first row of the
table on page 16. That says:
"Procedure: Access ECU (located behind
driver's seat within door pillar assembly)
(H8). Turn ignition on and
observe LED on ECU for codes.
Codes: Codes blinked out by LED are
separated by two second pause, then
repeated. For example: 2 blinks - two
second pause - 2 blinks = code 2 (H14)"
No tool necessary it says. however, i don't really know how to get in
the 'door pillar assembly'
link). My car is a *1987 Honda Prelude* which is the first row of the
table on page 16. That says:

Look under the drivers seat (from the rear seat side.) That's where
it was in the '86 integra.

Replace your oxygen sensor and see what happens. I have an 88 Prelude
and I think mine is out as well.

IMO,it would be wise to get the ECU **trouble codes** read before you go
replacing expensive parts.
Chances are,a trouble code would point you in the right direction.
You could also have loose or corroded grounds;the OTHER half of the wiring.
(or a loose or corroded connector)
BTW,I noticed today Harbor Freight had O2 sensor removal sockets(3/8"
drive) selling for about $5.

IMO,it would be wise to get the ECU **trouble codes** read before you go
replacing expensive parts.
Chances are,a trouble code would point you in the right direction.
You could also have loose or corroded grounds;the OTHER half of the wiring.
(or a loose or corroded connector)
BTW,I noticed today Harbor Freight had O2 sensor removal sockets(3/8"
drive) selling for about $5.
