I'm not a mechanic. I can change my oil and stuff like that. Need a little help to locate the right spot to put the Sea Foam in. I'm having low idle issues. Thanks in advance.

Use throttle body cleaner only which will work 1000% better then seafoam and much cheaper.With throttle body cleaner just unhook the air tube from the TB,start engine and operate throttle by hand(to keep engine running) while spraying,in short burst,TB cleaner into the TB.

Here's a video showing how to Seafoam a KJ. He shows you the vacuum hose to use. It will suck the Seafoam right into it as you slowly pour.

i found the closest vacuum line to the intake manifold and popped off the hose and slowly poured a little at a time while the vehicle was running at about 1500 RMP.

That should do it. I did the same and got only a tiny stutter and none of the white smoke that is supposed to happen when you really put it in. I was really careful because i'd heard about waterlocking the engine. Also use a can in the gas tank.

You can also by an aerosol spray trype of seafoam can that is like the throttly body cleaner. It comes with a plastic piece that wraps around the throttle body with the hose sticking in 1/4" from the throttle plate. Then you put the hose for the air intake back on and rev the engine 500-1000 RPM over normal idle and spray into the throttle body at the same time.
I gave it shot this weekend and it was extremely easy. I also go really easy on the seafoam and probably injected it slower than recommended because there was no white smoke.
Can't say it seemed like it made any difference either, but the Jeeps been running rougher than normal since i had the head gaskets replaced...
