throttle body idle screw O ring removal

[Simadowna119]

i have searched and only found a thread for the 2g removal but it only tells you how to see the ring.....not how to remove it... i have a 1990 plymouth laser turbo


i know that i can use a magnet to pull the screw out...but then what?...can i simply remove the the O ring with needle nose or something?...

basicly can i remove the Oring by just taking out the idle screw?....or do i actually have to take the Throttle body apart?



thanks..... answers are great but answers with pics are better

that o-ring is on the screw so when you pull the screw out then you can walk the o-ring off with your fingers, i wouldnt use needle nose unless you are changing it with a new o-ring.

Btw, the BISS screw is plastic. Good luck removing it with a magnet.

Some of the 1g screws were metal Tim.

The BISS o-ring just sits in a notch in the BISS screw. I typically use my fingers (if it's flexible enough) or a pick (if it's hard).

ok thanks.... yes my screw is definatly not plastic..... btw

Mine is metal also

If you take the throttle body off, you can push the screw out of its hole once its fully un-threaded from the inside with a small pick or piece of wire, that's what I did just the other day!

A magnet will work

Really? Do they still make those? I hate the POS plastic. It's so easy to strip the head.

I don't believe the metal one is an advantage over the plastic one really. I don't believe you can get them anymore from the factory though. I think all the BISS screw part numbers are superseded with the plastic one.

when you take the idle screw out, if you blow in the hole that the screw came out of should you be able to blow air through or not???...cause i took the screw out...blew in it and you could blow air through.... i also replaced the O ring and put tephlon tape on it and it didnt change anything

i guess its my ICS??? i unplugged it and started the car and it ran differently...like it just revved between 900 and 1100 rpm and you can rv it but it de-revs reaaaally slow..... and if i plug it back in its back to ideling at 300 and boouncing up n down and nat able to hold the throttle at on pace but able to rev it

The metal ones are much nicer. I'm guessing it's due to the expansion of the metal but after the motor is warmed up you can feel how tightly the screw sits in position. And you never have to worry about stripping the head of the screw anymore. Not to mention being able to remove it with a magnet if need be.

I found mine by chance at the boneyard. It was out of a Dodge Colt.

I used a razor to remove my BISS(screw all the way out then slide razor in crease and flip it up and out or stab the side of the screw and pull it out) and used that same razor to cut the old dried up o ring off and replaced with new o ring.(Razor was a refill for a box cutter)

Yes, you can blow through the BISS hole. It just leads to a hole in the throttle body.

Yep, bet it's that sensor that is acting up on you.

I have to laugh with my Laser: I don' have a BISS screw in mine. There is a rubber vacuum plug that is in my BISS porthole and it really seals things up quite nicely-no vacuum leakage at all.

I can hold 750rpm dead on.

I figured that I'm doing good with the idle, so why fuss with adding the screw..?
