Car Forum / Honda Cars / June 20062000 Accord mystery connectors
I finally got around to dropping the new head on my wife's car. There are two connectors for which I can't find a plug. One is a fairly large brown square one with a lot of wires feeding it that I THINK was bolted to the underside of the intake manifold. The other is an oval black one with three prongs bolted to the back of the intake manifold. The car starts but has a rythmic surge at idle and dies if I try to give it any gas. Alright, the clock is ticking, what are the mystery connectors and are they the cause of the running issues? Thanks in advance. Jim > I finally got around to dropping the new head on my wife's car.

Ideally, you'll post them so all can see them. 'kay? On my web site I posted a photograph of a "mystery nut" that fell off my car while I was grinding off rusty bolts a few weeks ago. The group nailed it within an hour. > I'll try to attach a couple to an email tomorrow. >I am nowhere near thee expert here. Ideally, you'll post them so all can >see them.

Oh yeah, I remember that. It was a fuzzy picture and you took some heat for it. It just happened that I had just pulled the head off my wifes Accord and yours sure looked like one of the manifold nuts. > I finally got around to dropping the new head on my wife's car.

Do you have a Check Engine light lit? > The car starts but has a rythmic surge at idle and dies if I try to > give it any gas. Fluctuating idle is mostly a sign of an AIR LEAK, NOT low coolant. There are several sources for air leaks. Both the dying and idle could well have to do with those connectors. > Alright, the clock is ticking, what are the mystery connectors and are > they the cause of the running issues?

That's because that round thing in the last bit is a 'zero'! change it to a lower-case 'o' and it should go.

Thanks Graham. >>> What address should I send them too? tegger@tegger.c0m bounced. >> >> That's because that round thing in the last bit is a 'zero'! change >> it to a >> lower-case 'o' and it should go. Yeah. That's an anti-spammer munge. Sorry about that, but it's necessary these days. > Ohfergawdsake... Thanks Graham. They're up! http://www.tegger.com/hondafaq/misc/nasty/ I made a smaller version of each pic for those with slow connections. Now I'm sure the black one is the throttle position sensor (3 contacts gives it away), not the IAC connector.

It's a good one. > Now I'm sure the black one is the throttle position sensor (3 contacts > gives it away), not the IAC connector. After some studying, I think it IS the IAC, not the TPS. Notice the coolant line going to it. Anyone else see the exposed pipe end below the black thing? Looks like a PCV part that's disconnected to me. I wonder if there's vacuum in it at idle?

The picture of the black oval connector was taken on the replacement motor which is not installed. There was no way to photo the connector while the intake manifold is on the car. >> Now I'm sure the black one is the throttle position sensor (3 contacts >> gives it away), not the IAC connector.
