No need to. Pretty easy. Get a cup of water, preferably something like a 24 to 32 oz. cup. With the air cleaner off, hold the engine RPM at 2000 RPM or higher and dribble the water from the cup, which you've pinched to look like a spout on top, into the carb or throttle body. Go slowly and the engine will bog a bit. Stop and let it recover. Repeat until the cup is empty.

The water cools the carbon quickly causing it to flake off and gets removed on the exhaust stroke. You can try using chemicals such as seafoam but water is shown to be much more effective.

Some say the water also causes a spike in cylinder pressure that knocks it off too. It's cool if you look up pictures of engines with coolant leaks the cylinder with the cracked/leaky head is nice and shiny and usually the others are all caked with carbon. Read you can also use ATF but that makes a lot of white smoke.

I would never pour lubrication oil into a gasoline engine's intake

Multi fuel engines such as those in military m35a2s can be run off of used ATF if filtered properly? But yeah I'd definitely stick with water for decarbonizing.

Anybody know what this plug is for. I'm getting tired of the is big roll of like 5 ft long yellow wire under the dash. I followed it up to this plug. I don't want to cut w yellow wire off in case it's for something important. Anyways, so the the plug it goes not also has a purple and black wire, the black wire goes to the ground under the dash, and the purple wire goes to a plug on the steering column. The purple wire then comes back out of the plug and splices into a red wire that goes into the wiring harness for the jeep.
Here's the plug
The long yellow wire
The ground

More pics!
Here's the plug on the steering column that the purple wire goes to
The red arrow is where the purple wire goes into the plug, the blue arrow is where it comes out.
Here you can see where the purple wire (blue arrows) comes around and is spliced with the red wire and goes Into the harness (green circle).

i neglected to get an alignment after lifting the jeep for a few months and now my front tires wore significantly more than the rear. To some extent I read it could be normal, but I feel they really wore fast.
My question is, should I proceed to rotate them? I put maybe 6-7k kms (I guess around 4k miles) on them since I bought them new, and would like the best setup for their current condition. They have about 3-4/32 of difference between front and rear. If I should rotate, what's the pattern I should follow? Left rear on right front, right rear on left front and both front wheels on the same side but rear? Thanks!
