tube in intake

Trying to clean the throttle body of my 1990 Grand Voayager today.
As I was spraying the throttle cleaner into the butterfly, I
accidentally blasted the plastic extension discharge tube that
was attached to the nozzle of the spray can into the intake
manifold. I could not recover the tube without taking the TB
out. Would there be grave consequence to the car if I left
the tube there for good?
Thnx,

Yes, leaving the plastic tube in there is a very poor idea. You're going
to need to remove the TB and get it out of there. No great tragedy;
removing the TB is really the only way to clean it properly anyhow.

 

Thanks for the response. What are the possible consequences if I do
not do anything?
I was hoping that the plastic thing would get suck in the chamber
and get melted
at no time...
The car had already been driven after the incident. I did not notice
any problems. You are right. I should had taken the TB out
in the first place for a more thorough clean job. Just a bit
lazy. And I did not want to replace the gasket....

Asked and answered.

 

It is probably still stuck in the manifold. If it gets past the manifold it
would be a miracle if it made it completely into a cylinder in one intake
stroke. If it did and the mass was low enough then your correct in that
it would probably be melted and blown through the exhaust.

But much more likely is it will go partway into an intake valve, the
valve will not close all the way, the cylinder will fire and blow back
into the manifold, the classic backfire. It may take a few strokes to
clear the cylinder. If the valve gets propped open for a long enough
time the hot conbustion gasses could heat it up and possibly damage
the sealing surfaces. If the valve stops sealing then you will lose
the power in that cylinder.

Well then it's a moot question, really.
