hey guys
i've just installed a skunk2 IM and TB, it runs but the problem is its misfirering and i cant figure out why
its been tuned for the stock IM and TB, could that be the issue. the tune???
also its running heaps rich blowing black smoke on idol
im pretty sure all vac lines are on
any ideas ppl

You can reset your ECU and see if that helps.

If installed correctly it should idle like stock manifold. Check all sensors plugged in properly.
What is the size of the IM and TB?
If they are different, the air does not flow smoothly into the engine. That's why it might has problem with idling

ok guys update
i've fixed the misfiring problem, now the only thing still wrong is that it wont idle below 2k rpm
just holds it at 2k and sometimes hunts
tried adjusting the screw, doesnt do much...
could a faulty IACV valve be the cause here??
any ideas?

Sounds like the Map sensor but I'll wait to see what the pro's say :)
What was the cause of the misfiring?
czy_sol87
25-06-2008, 06:51 PM
it was partly the map sensor not having a vac line anywhere and the EVAP vac line not having a big enough vac hose, so i've used some T peices and taped into other sources for vac
can anyone tell me what these three holes at the top of this skunk2 TB does??

sounds like an air leak
the top hole where the map sensor plugs into?

vaccum leak. PLace your hand over the throttle body and if it idles, start searching for the air leak.

or throttle body cleaner all over it and if the motor sounds like its gonna die then leak leak leak leak

well first of all when you installed your TPS on your new TB did you check to make sure the voltage is what it should be at idle ? WHat is your voltage at idle should be about 0.5V at idle and about 4.5 at WOT.
Once you have the right, adjust your idle screw, and or check for leaks

from what size to what size?
oversize too much may have idle problem..
i previously have the same issue, but got it tune and now it's all good..
u may need to adj your idle valve ctrl and tb position...

i have a feeling its the TPS, but will have to have a look 2moro

Easiest way to tell is to check Voltage for both TPS and MAP, these tell the whole story :)

Those holes are there for the MAP sensor.

ahhh makes sense....but there are no "connections" or fittings to attach vac hoses to, so i blocked it off, just incase it might have caused a vac leak

Normally there isn't supposed to be. The MAP sensor slots straight in to it with two screws at each end holding that lil' sucker in :thumbsup: . In saying that, yours isn't exactly a typical setup ey?

well i'm guessing his got an delsol which uses a map sensor which sits on the fire wall instead for on top of the IM.
But yeah, probably could be any of what people have said. TPS, MAP, IACV or vaccum leak.
czy_sol87
03-07-2008, 06:02 PM
yeh its a delsol with the MAP on the firewall
pretty sure its not a vac leak, checked around all possible areas and it seams like nothin is missing, plus if i cover the TB the engine stalls, if there was a vac leak it would try and stay on
pretty sure its the IACV cause it was playing up when i still had my old IM/TB
i'll just have to wait till i got some spare cash before i can get a new one

want some cash? hows the car going? fixed it yet
man i had the same problem on, mine. you need to block that hole/port that houses the sensor.
i have an ITR edelbrock TM with Skunk2 IM on a obd2 B16, idles like stock.
might want to replace your plugs when its goes back to normal idle.

u mean that little hole inside the TB that goes to the IACV???
u sure thats the solution to this problem????
what did u use to block off the hole?
the port plus 2 threaded holes on top of the TB.
i got my dad to fab up a small aluminium plate, i can get a pic if u like.
basically an ITR tb on a obd2 b16 is NOT a straight swap like some ppl want on about but if u block that hole and have no other leaks and no codes it should idle like stock.
you dont have any codes right?
czy_sol87
05-07-2008, 12:57 PM
yeh no codes
yeh a pic would be good just not too sure which hole ur talking about
i've already blocked off the hole at the top of the tb where others have said the map sensor is suppost to be...

oh really, sorry that was the hole i was talking about. u shouldnt have problems if there r no leaks now. what did u block it off with?

just a spare bolt
when i start the car it idles at 1.5k, then once i start driving a bit at moves up to 2k rpm

oh ok, u sure it seals? i sort of did that, then actually used a gasket and properly tightened my blank and then it was sweet. u sure there is not possibilty of a leak?

could be that bolt, i might try some type of gasket sealer on it
but i noticed that i didnt effect the rev's when i held my finger over it, so that might not be it
plus if it was a vac leak the engine would try and stay on when i cover the TB, but it doesnt just stalls straight away
i have a feeling its the IACV cause they usually stuff up on these old hondas
fair enough man. i wish i could help more.
but as u said the finger thing, i did that and noticed nothing but when i used the gasket and got a perfect seal.
oh well, i hope its the IACV so its fixed. check ur plugs after, remember :p ;)

check that air sensor on the manifold, sometimes ppl put the IACV plug into the air sensor then it pops and also check the throttle body gasket if its on the right way
czy_sol87
06-07-2008, 11:05 AM
all sensors are on properly
if they were not then the ecu would throw a code and engine check light would be on

nah dude, been busy at work havent had time to work on the car, but i'm gonna get a workin iacv in the next couple of days, hopefully that works

ok cool i hope thats it. plz let me know :thumbsup:
i like to read/hear about b16s (wish it was better news tho lol) :)

i went down to AK Motorworks yesturday and andy had a quick look for me (thanks for that dude)
he rekons there is a vac leak somewhere, also iacv is on its way, so his suggestion was to check all vac hoses etc again and make sure there are no leaks, then once i've solved the vac leak problem to get a new iacv
i'll take a look next time i got some free time so hopefully i'll have this problem fixed within the next week or so
will keep u guys updated on my procress

i had this problem before and what caused it was the gasket between the IM and TB.it didnt fit well so i had the get a new gasket from honda.$8 and faulty TPS after ive changed both everythings all good.
are you no longer running a FITV?
if so that could be your prob
czy_sol87
09-07-2008, 02:52 PM
yeh im runnin without the FITV now cause there is no place to put it on the skunk2 TB
isn't the FITV suppost to keep the revs up in cold starts then go back to normal revs once the engine is warm...
if thats the case then then engine should just start at normal idle speed all the time, no matter how cold it is
i also have no FITV and mine idles normally. im pretty sure thats not it.
:thumbsup:

unless the idle screw adjustment is out..
maybe put stock TB on with fitv and see if that rules out anything
good idea imo ^ :thumbsup:

hey guys still got this problem....my mech had a quick look at it when he was installing my new gearbox, and said he couldnt find a leak, and its just because im running a bigger IM/TB that makes it idel high, but i dunno cause egSi..ur running the same thing and have normal idle...im not too sure where to start now
so far i've pulled off the TB and put the stock on back on but the problem there was that the stock TB is bigger(where the TB sits on the IM) than the new IM so from the back it leaks air and doesnt rev at all, it just jumps to like 5k rpm
what i might have to do is when i got some free time pull it all off again and reinstall it to see if i missed anything the first time
if anyone has any suggestions please feel free, never know might be the cause LOL
damn that sucks man ^
i just went for a drive today. i have pulled so much shit off my B16 and still idles OK, i wish yours did too :D
how does the car perform under load? fine?
czy_sol87
06-09-2008, 10:53 AM
yeh it performs fine, needs a retune though...
does it help if i tell u that on cold days the first time i start it it idles at 1k?? but as soon as i start to rev it it will stay at 1.5-2k rpm
others have said it might be the tune, but it cant be cause my tuner set it all to 0 to try and make the idle go down but that didnt help

sounds light a sticky throttle body
maybe try a dif IACV and make sure it is sealed fine..

i've used my stock one, then recently changed to a different one, didnt help
TB is fully closed already
votek
07-09-2008, 03:12 PM
so the higher idle is not normal? ive just installed my spoon t.b and my idle is at 1.5 to 2k rpm
need someone to help in melb too.. any mechanics?
My car had the same problem as yours after i changed to ITR TB. It idles between 1.2k-2k rpm and it keeps going up and down.
It starts to be better after driving it for 2 weeks, it idles between 900-1.3k rpm.
After about 500km(cant really remember), it suddenly idles just like stock. My VAFC shows that it is around 780-8xx rpm for the idle now.
Before it changed back to normal by itself, i tried to reset the ECU but it doesnt work on me. I cant really think of anything but just keep drive it as my daily drive. So maybe just try to drive more :P
czy_sol87
09-09-2008, 12:14 AM
LOL yeh driving helped a bit moved down from 2.5k to 1.5-2k rpm
but have a look at the first post it was like 2 months ago and the car is daily driven
votek
09-09-2008, 02:29 PM
but the thing is the car shouldnt have to be daily driven to fix the problem lol
hey mate have u tried starting the car, pulling the vacuum line off the booster? That would replicate a mad vacuum leak. revs should jump up, if not you definately have a leak.
sorry if this has been said but it was something i thought of yesterday when working on my car.
i hope u fix this shit asap :thumbsup:

sounds like you needed to do the IAC reset procedure, thats all.
