Finally the engine turs on :rockon:

But besides that, Ive run into some problems. One of the sensors on the throtle body broke while I was swaping it in, do I need that sensor and about how much is it to replace? Also I noticed that on the harness from the GSR has 2 extra plugs; one looking like a ground or power (its clipped) and the other looking like a connector. Where do these go? I cant seem to find anywhere to plug them into. Also one of my vaccum lines is free and roaming around and I cant seem to find where to plug it into the GSR. Dont worry Ive attached pics.

Also, how can you tell the year of the engine??

The broken sensor is your throttle positioning sensor. You NEED that sensor, you can pic one up at a scrapyard, cuz I think it's pretty expensive if you pick it up directly from Acura.

Your clipped wire I have no clue what it could be. For the other one, considering it's on the tranny side of the engine bay, it might be your reverse light switch or an O2 sensor. Not 100% sure though.

And for your loose vacuum hose, I'm not too sure what that sensor might be for. I was thinking it might be your EVAP purge solenoid, but I saw it in the last picture. What is that other hose on the sensor hooked up to?

You can probably recycle the TPS from your old D engine.

first two pics are the TPS like everyone said above

third pic looks like the alternator/starter wire cut of course. it should have a positive battery terminal on the end of it. the connector looks alot like the O2 sensor plug.

fourth pic is the Evap purge valve. one side connects to the charcoal canister, other side goes to the intake before the main throttle butterfly.

date of manufacturing should be stamped on the front of the head.

Yeah The year should be stamped right above the Mani fold in the front. Remember if it says 94 then it's a 95 motor. If it says 93 it's a 94. So on and so forth.

I don't think it is the EVAP purge. Look at what is bolted on top of the intake manifold, that's the EVAP purge.

Relic1

you are right, my bad. I forgot there is a different EVAP valve for the GSR.

theguy386 - is that connected to the engine or the car?
I'll bet it's connected to the car and not the engine.
it sure looks like this.... (next to the TA arrow with the breather cap on the top of it that was obviously lost off yours)

that's the EVAP valve for the civic. use the one for the Teg and throw the civic one out.

This goes to the firewall where the other vac hose is at (its a canister looking thing).


Also when I took off the throttle body so I can change the sensor I noticed that theyre not screws or nuts that can be easily taken off. Would I have to take it to a mechanic so it can be taken off??
