its not the ICV and not the throttle sensor. it was clipped i place so it seems like it would only be like a 7 inch radius from where its been clipped.

its a slightly smaller clip interface than the one that goes into the bottom of the throttle body.

sorry to post something probably simple, but i am dead in the water with this here

Looking at the engine picture this is a 924S, I assume?

Does your intake manifold have a weird black fitting sticking out of the top rear, with a missing wire?

jbob

yes 924S - thanks!

no the only wiring input is the one at the base of the throttle at the front of the intake manifold...

i took this all apart a month ago, before sending the injectors off and getting busy and i just can't remember this thing. the inside of the clip is clean so seems like it was connected with something

jbob

maybe the knock sensor? can't remember ever seeing that bloody thing.

924S doesn't have a knock sensor.
the 924S (at least some?) had a weird little black solenoid valve on top of the intake manifold next to the oil filler cap that had an air hose coming out of it, and a little electrical connector. no idea what its for...but i've seen it before on someone's car.

jbob

shoot. not seeing that. took my AOS back off to see if some connector was hiding back there. nothing...

it sucks because this has me totally stuck

jbob

could this have been a vestigial wire left unhooked the whole time? I'm thinking not, but i just don't recall unhooking it when i started this fuel line project

Arominus

if it was unhooked the inside would be mega dirty, if its clean, it was plugged in.

jbob

so bummed. i have literally stared into that engine bay for hours on multiple days... not seeing diddly

I have an 1988 924s. The engine is out of my car. About 4 inches below the #1 plug and a little bit to the front is a 2 pronged plug in. Mu is green. It is just to the left of the single wire plug in. I hope this helps.

jbob

thanks - I think that one by the 1st cyl is a thermostat. this wires is clipped to the main DME bundle and won't quite even reach that far. it has a radius of barely reaching the front edge of the AOS and maybe down past the balance shaft tube.

this is the weirdest thing...

Is that a 2 or 3 prong connector?

jbob

2 prong for the mystery plug

I looked at my engine again and only found the one plug in. I suggest you go to 924.org. They have a 924s section. Maybe one of those guys could go look at their car for you. If you find out let me know. I may have the same problem when I put my car back together.

looks like it might be a fuel injector wire..seems to be part of the brown harness..am I looking at the right wire?
