Default Seafoam treatment through intake hose?

Whatsup gents? and ladies probably haha
I've got a 2001 Camry LE and I'm having a high idle on it, spoke with a few people and the suggested cleaning out the fuel injectors. Best way is a can of seafoam in the tank and an induction cleaning right?

I know there is usually a vacuum hose that goes into the intake manifold somewhere that you can unplug temporarily and use as a straw to suck down the a bottle of seafoam. Let it sit for 30 minutes and then pretend that your car is on fire while you smoke down the highway .
Can you guys suggest a good vacuum line to use for that? Or maybe another remedy for a high idle?

Usually, high idle points towards dirty IAC valve. Before you do any seafoaming, which is good in both ways, (Through gas tank which cleans out your fuel system and injection system and vacuum lines), clean your throttle body and IAC valve. If you're IAC valve is too dirty, replace it with new and you'll have normal idling rpms.

Sounds good xspeed, is carb cleaner safe for the IAC valve? or is there a special solvent? I'll take a look through the forum. Thanks again

^ I cleaned mine with just water but any solvent (not highly corrosive) should be fine. Just soapy water would suffice but like I said, if it's too dirty beyond cleaning, getting a new one would save you time and risks.

Just did the seafoam treatment through the brake booster line, pulled the line right before the small white filter and sucked down a bottle of seafoam in about a minute.
Let the car sit for about 30 minutes and drove around for 2-3 miles while people were giving me the most concerned looks ever! It's always a fun task. Going to change the oil in the next few days also, i'm sure there is a lot of grime in it now.

How's the idle? Is it still the same or did it lower a bit?

Idle didn't really change. I'm thinking maybe I should clean that IAC a little more... I sprayed intake/carb cleaner into the slot on the bottom once I removed the intake tubing but maybe it needs a better cleaning and some compressed air. There was some brown residue that came up when I sprayed the cleaner in the slot. Car still has a semi high idle at startup but after a minute or two of idle it drops down to 800. Any other ideas on what should be done to remedy this? Replacing the IAC valve? Does the Mass air flow play any part in this?

The MAF won't change anything if you touch it. It's probably the IAC. Spraying it from the outside won't do much. You need to completely take out the IAC, clean out the inside completely and reinstall it and see if the idling is still the same. If it doesn't do much, then you probably need to replace it with a new. I would probably clean it first before getting a new one. Does your RPM drop after you warm up the car? Does it drop low enough to shut down the engine?

Here's a link to another forum where a member shows you how to do it.
