Does a vacuum hose attach to flapper

[SeaMonkey]

Ok I really don’t want to put this out there but
I recently purchased a 2003 with 9,000 miles
On the way home after buying her I was having low end sputtering and basically wouldn’t idle. From previous experience I suspected clogged fuel injectors, I sent them to a shop in to Torrance cali just got them back
Report showed dripping and overall terrible spray pattern the shop did their magic and not the fuel injectors are perfect.
The problem I’m having now after they where installed is a Bog down up to 3,000 rpm but after that she runs like a rapped ape!
I’m going to install new plugs today
But I have also noticed there is no vacuum hose attached to the the flapper valve under the air box is this normal?

You need to find the hose that should be connected to the flapper and connect it back up, just so it doesn’t leak vacuum.
It may possibly be blocked off by the previous owner but you gotta find it and check.
Its teed off the vacuum hoses going up to the throttle bodies.

Thanks for the reply’s
I found the hose hooked her up
But I’m still getting a ruff idle and some bucking under 3,000 rpm
Next I’m putting in new plugs today
Hope that helps

My problem is solved
So after fuel injector cleaning
And putting in new plugs she runs like new!

Thanks Brother
The process took three weeks and there
Where times when I was ready to take it to a mechanic

Looks like YOU are a mechanic!!
You know, never underestimate your own abilities . . along with a few pointers from us oRg members that have a ton of experience (I'm a working motorcycle tech) you will get the job done, eventually.
Also, spark plugs can misfire and cause poor running issues so easily, so always go with the basics first when addressing a problem such as you were having.
You did well getting the injectors out and sending them off to be checked . . . most people would never get in that deep, that's a 'mechanic's' territory lol.
