couple questions

[[JUDGE]]

1. I have a 92 model vp executive and was jst wondering ive herd tht removing the bellmouth gives it a bit more go, is this true and ive herd tht some vp's have the bellmouth already removed, would mine still have it or not?

2.And my roof lineing has all of a sudden decided to start hanging, after recently my m8' been sayin how good condition it is in, glrr now its begging to fall on the driver/passenger side front, how do i go about making it all tightened again, or even changing the colour, id like to make it either black or white.

[Matt_vp]

the bellmouth is a resticion in the intake and is only there to smooth idle and distribute the air evenly to all cyclinders. I did notice a bit of differance in the good way after taking it out.
and i think the is a thread in the how to section about fixing roof lining.

[[JUDGE]]

so its for the best removing the bellmouth, well id like to remove mine , ive tried b4 but didnt know what i was doin, can ne one describe how to do it? pics would be great too!

[anton1o]

Is a DIY on how to remove the bellmouth, its an easy job if your car is a Series 1 or 2.. If its a mix series like mine youll notice a thermostat gets in your way of the job..

And the roof lining can be fixed yourself, or most upholsterers will do the job for 100bux

[[JUDGE]]

the sites not working buddy, u sure its the right one? lol thx ne way

[Matt_vp]

u have to change the 33 with ee

or VN Series 2 - VR Bellmouth on this site. some say that modding the bellmouth rather then removing it totally is better again

[Matt_vp]

i tryed modding the belllmouth but didn't find any better

[[JUDGE]]

hey ive taken most of the things off the throttle body, ive taken off the front 2 screws but its not coming off to get out the bellmouth, is there a screw at the back somewhere:S

[immortality]

hey ive taken most of the things off the throttle body, ive taken off the front 2 screws but its not coming off to get out the bellmouth, is there a screw at the back somewhere:S

there are 3 bolts/nuts holdeing the elbow on the manifold and 2 bolts/nuts holding the TB on the elbow

[[JUDGE]]

hey well, i finally got all the bolts/pluds/hose's off, got about 90% of it done, was up to taking the throttle body off and the frigen thing wouldnt come off i dont know why but it jst ****tin me off and its hot, and i got work later tonight, so i ddint wanna mess ne thing up so i jst put it all together...grr and now my intake's ****tin me off the stupid connect tube wont go round the intake pipe GRR

[[JUDGE]]

AHHHHH i started my car after i put everything back together, i swear!! i put everything bak the way it was, and i started my car and its over reving hard!!! like its full throttle, but i loosened the cable as much as it could and it still doing it....plz help !!!

[Matt_vp]

u might need to reset the IAC (idle air control valve)

[1991_Vn2nV]

Hold the car at 3000 revs for 10 seconds to reset the IAC.

[[JUDGE]]

as soon as i start the car tho, it shoots up to like 6000 plus revs, it scares me i dont want it to break lol...help lol

[azkwazere]

make sure you TB isn't jammed.... or your TBcable isn't stuck.... IAC wont make it rev at 6k... thats extreme..lol....

[[JUDGE]]

well i dont have a rev gage, but the rev's go through the roof!! and im not touchin the accelerator, and i losened the accelerator cable till it was completly lose and it still goes nuts!

[azkwazere]

Pull the TB off again and make sure the butterfly is closed... if its jammed open it will rev at "full throttle"

aZk.

[[JUDGE]]

im not an expert yet, but whats the butterfly, is tht one of those things tht sits in the tube and spins open and closed?

[azkwazere]

The throttle body works similar to a keg tap. Inside the valve, there is a round piece of meltal(TB, plastic for keg) that spins on an axsis. In the closed position, the round piece of material will be blocking the path of valve... imagine a 20c piece against garden hose with a skwewer stuck directly down the center of the coin face. If you placed the coin ontop of the hose (flat, covering it) air willhave difficutly in flowing out of it, rotate the skwewer so the coin starts turning and you notice that more air can flow as the coin turns. Imagine now that there is a string attached to the skwewer so when it is pulled, the same hting occurs... this is your throttle cable.....


The coins job in the TB is to regulate air flow... more open, more air.... it is known as a butterfly valve system.

You want to insure that the valve is not stuck! If it is, maximum air flow will be passed into engine = high revving.

Hope that helped.

[Matt_vp]

ok the butterfly is the roundish bit inside of the throttle body that rotates when the throttle is opened to let the air in. these motors sound very loud even at 3000rpm. Try pulling the intake tube off and seeing how the butterfly is sitting, open, closed, half open? even better if u can take a pic if u cant work it out. if it is fully closed with out the go pedal pushed down that is good? if it is all god there try disconnecting your battery for a couple of mins then reconect it start the car, see what happens? is still reving high? are all the bolts tight and gaskests in good nick so there is no air leaks? your throttle cable should be as tight as it can go without moving the butterfly..
have a go at that and tell us how u go..
Matt

[Matt_vp]

did u reconnect all the hoses on the elbow?

[[JUDGE]]

yea thx matt vp and azkwazere, tht seem's like my problem i reckon, and yes matt i did put all the hoses back and and yer lol, ne way back to the bellmouth does ne one know why my throttle body wouldnt seperate from the plate with the (3800) on it?, even tho all bolst/hose's were undow :S

[Matt_vp]

it might have lots of gasket goo on the gaskets or no gasket and heaps of gasket goo, how hard did u try. give it a wriggle while pulling. lol
there r three bolts/studs, one on each side and one on the bottom to the drivers side of centre. if all these r undone then it should just pull off.
