Vsig: 96, 8v , Spanish made (Santana factory) with DLC moved from battery front to RF head light shell rear, like our 96s but ours are all 16v.... my DLC page cover that......
Yes, there are some changes here, as EGR also, my vitata has it like carburator model I saw it in the manual in page GJ-18, without coupler to connect to ECM, but the manual said in fuel injection system GE-89 that EGR is electronic valve..
Have to be more differneces too..
so...
if the pinch test fails , duty cycle can never be set.!
when the pinch test fails, that means there is at least 1, large vacuum leak.
You are right, you can see below what I think is the best test..
the one in the center of the TB must not be cracked, but is not , the TB is new.
Yes, that gasket is new and it's in right condition, it came from Santana installed between thw two semi-body..[/color]
what the air horn gaskets only keep out dirt, in the induction and do not change idle speeds or effect duty cycle ever.
You are right, it don't change idle spped but because I dind't know that and as I saw it a little deteriorate I changed it..
[/color]
the 8v fails pinch test for the following.
all vacuum leaks below the TV (throttle valve buttery fly plate)
I suspect that also, you can sse below why I say that..
[/color]
TV plate not closed 100% for any reasons what so ever, at idle, Dashpot is retracted now.
TV plate is butterfly in metal color ? It closed 100 % I saw it when I install air horn gasket, I retrated by hand the D/P and I saw nad tested it closed 100 %
vacuum hoses. leaking, any
I installed all vacuum hose new but not from the canister fuel tank [/color]
TB base gasket leaking
That is one of the more suspicious candidate after you told me about those five holes tha must to be covered..
the TB base gasket missing or cut by and the the cutter, man allowed the 5 small hole there to be OPEN, (wrong) they must be closed, off.
Yes, that is I mean..
this 5 holes are factory drilling's (they are called) that create internal passages, when manufactured, and most be closed.
brake booster leaks. (some do , randomly , each brake pedal movement, common on old cars this, easy to proof, block the booster hose)
I'll do that test in that booster too.. [/color]
EGR base gasket leaks, or EGR main cracked in half, as they are loth to do.
When I did test ISC air hose pinched and bleed was closed also, and the idle speed become drop 400 r.p.m I pressed with my finger EGR diaphragm and then the engine stall.. The manual said also when the engine is in idle hot, pressure EGR with finger and the engine have to reduce or stop,..
I'll do that test too..
intake manifold gaskets bad. (or missing)
I checked it but I can't see nothing about, but is another possibility, I can change it too..
IAC stuck open, its new, but the water hose sure can be clogged, and ISC is not at 180F (IR guns show, 170f about)
I'll see that also..
as long as the car has vacuum leaks , any other steps is useless,. Idle speeds, spark timing, and duty cycle setting.
totally useless.
Of course..
tests? (hot engine all)
with the HOT idle bleed screw turned fully CW, In, what is rpm now hot? not pinched, (can be 800 or rpm drops greatly as ISC loses control)
then
with the bleed screwed in, what is RPM now hot, then ISC hose pinched. engine must stall
with bleed unscrewed, fully , (out removed) the pinch test usually does 400 rpm. at least. the bleed is the only air supply (pinched)
I did that test: when ISC air hose was pinched, it drop at the middle of the gauge toy, then with that air hose pinched, I close the bleed screw to the end gently, then the idle drop to the white line next to 0 in gauge toy, but the engine don't stop..
You can see in this video the true problem we are treaying to compare it with the following, you can see also I give a little accelerate to drop th idle to 800 r.p.m
like I'm doing from about four monyhs ago..
I tried to insert video by GE.TT shar,e but had been unssuccefull, so I have to use YouTube again, just three houres to finish this post..
Because I have to use the keyboard with two finger and looking the screen all the time, if I try to run, I get mistake to expot..
https://www.youtube.com/watch?v=4TjErgLE...e=youtu.be
You can see in this second video what happen when the engine is hot and I start it but the ISC coupler is disconnected, after some seconds I connect it again..
I can't insert these vidose and some photos with GE.TT, for not overload the photo gallery, but the forum said 'you can't because 30 images is not allowed, only 10..
https://www.youtube.com/watch?v=I8SwYEyLmqs
Next video is probably the most evidencial test I did, I bloked the mean air entrance with my hand.. But the engine don't stop, you can hear that sound, as a water pump does when any bearing is in bad condition.. It seems like a flute or other instrument when the air is entering..
Sound above the engine but I think nearly to the TBI..
What will be it ?.. A hurricane ?
I did it twice..
You can hear a car leaveng the parking too..

Well, I think we have a huge leak as you say, but I'm very content because if is so, that mean there are not problem with TBI or ISC, IAC failing or duty cicle, at least to do it later and in right condition witout any leak pending..
I think the vitata is going to be OK before I learn to put color in a right way in the Forum, of course too and sorry..
Perhaps is OK now..
Well, I have to go now..
We in touch later..
Cheers!!
