ok, here it goes. As you can see in my sig i am building a 92 hatchback which is obdI
the motor i am using is a d16y8 which is obdIIa
this has been a battle to get this motor to function correctly in an obdI setup
all my electronics are currently setup just fine. all sensors are plugged in, i had to swap out the alternator and dizzy with obdI parts.
So the only thing left was running all of the vaccumm lines. This is the hard part, i used this article from H-T.com for that, ARTICLE.
There is one slight variation. he has a d16z6 throttle body, i dont. so the part on the evap canister that goes to the throttle body is not hooked up at all.
You will also notice in the article that there are 2 lines that run out of the front of the manifold, one goes under the manifold and is connected to the pcv. I have no idea what to do with the other one, in the article it is left bare.
So I fire up the car, it starts and idle like shit, i hit the gas, it bogs down and dies. With the hose from the front of the manifold plugged, it idles better but still cannot accelerate, im pretty sure its leaning out.
So my question is, what do i do. do i get a d16z6 TB and install that so i can hook up that other vac line into the evap canister, or do i get a d16z6 manifold and swap the whole damn thing. or is there something else wrong with my car??
booyah, 99_Civic_si came over last night to troubleshoot the setup. We found that the wiring on the Throttle Angle Sensor was fucked up.
Started with pulling the codes
Found a code on the TAS
Andy explained how that worked. told me that at rest, u should get a reading of .45v and at wot u should get around 5v
we were getting a reading at rest of 4.8v, really fucked up
tried a spare, same thing, we concluded that my wiring was fucked, and that i should re-run the wiring for that to the ecu
So today i was looking through the manual for the ecu diagram. found a page for troubleshooting the TAS. went through the flowchart with my trusty multimeter and figured out that the ground wire for my TAS was bad.
I ran a wire directly to the ecu for that. Went back and checked voltages, it was correct.
I went ahead and clocked the TAS so that it was reading .45V at rest.
Put it all back together, and it was working. Car sounds much better. and best of all no CEL’s. Thanks a lot andy, i owe u one.
now onto my laundry list of things that need to be done.
