Lots of things.

Do you have a carburetor or fuel injection?

In the US market, 1987 was the last year for carburetors on Civics. I don't
know if they were still available after that in other countries.

The question now is dual-port or multiport/point?

I think single-port throttle body injection until 1992(?). Maybe only the
Si's got multi-port. Elle, does your car have single-port or multi-port?

Do you mean does my 1991 Civic LX have an "essentially throttle body system"
(and so is single port?) or a fuel rail (and so is multiport?)?

You're over my head here. I know my Civic has a dual-point fuel injection
system, which means it is, according to Chilton's, "essentially a throttle
body system." It has a main injector and an auxiliary injector in the
throttle body.

My Chilton's for 1985-1995 Civics otherwise isn't too terribly clear on
this. It implies (from drawings and the text) for 1985-1995 Civics:

Dual-Point FI was used from 1988-1991.

Multi-Point FI was used from 1985-1987 and then again from 1992 to 1995.

Then it seems to ignore the Si engines. So I don't know where the SIs fit in
here, even after looking at their throttle bodies and comparing them to my
91 Civic's.

Autozone seems a bit more clear, differentiating the fuel injection designs
according to engine size: 1.5 liter vs. 1.6 liter.

But like I said, I'm out of my league on this. Just posting at your request
and to try to learn more.

That's my answer. Two injectors in the throttle body instead of one in each
intake manifold runner.

Really? Back then only high price-point cars got multi-port FI, like the
Toyota MR2 and Honda CRX. I have the Helm manual for the '88 Civic CRX. Its
D16 engine had multi-port.

Looks like multi-port was across-the-board starting in 1992, probably on
account of emissions laws.

Multi-port is easy to identify. Each intake runner has an injector which
looks a bit like a tiny spark plug. There is a a "rail", or square tube
connecting them together.

Gonna have to do some more checking then. Thanks.

Great. That wording confirms my reasoning (on the basics, anyway).

Its
> D16 engine had multi-port.

That is surely a 1988 CRX Si, with a 1.6 Liter engine. From www.slhonda
online parts site, the Si appears to use multi-port.

By contrast, the 1988 CRX DX is a 1.5 Liter engine (D15 engine code) uses
the "single port" (two injectors in the throttle body) design.

So again, I think my "Civic/CRX/Del Sol Chilton's is not quite treating the
Sis. (Is there a Chilton's just for the CRX Si circa 1985-1995?)

I can't find a drawing of the rail at Majestic for the multi-port engines.
Not sure what category to check (and I've checked a few).

It's been an education, so likewise.

Note for the archives: I for one am talking strictly about United States
Hondas in this thread. There does seem to be some variation in the fuel
injector designs available outside the U.S.
