Yeah, I'd ignore most of what the apparently unintentionally douchey douche had to say. The jobs listed are things that someone with zero mechanical experience can do with little or no risk of damage.

Don't...

1. Cross thread the spark plugs when you bolt them back into the head.

2. Allow any debris to fall into the cylinder when you remove the spark plugs. The hole they screw into goes directly to the cylinder/combustion chamber so be careful. I always use an air compressor to blow the gunk out from around the spark plugs before removing them.

Do...

1. Use a Sharpee or other permanent marker to label the spark plug wire locations (1-6) on the distributor cap so that you can use it as a reference when installing the new one. The coil wire goes in the middle.

2. Collect the tools you'll need... 3/8ths ratchet, 10" 3/8ths extension, 5/8ths (I think?) spark plug socket, and a Philips head screwdriver.

3. Properly gap your spark plugs at .035

4. Ask us questions if you run into any problems.

 

I'm pretty new to all of this too, and I just replaced my spark plugs no problem.

Don't let anyone try to discourage you. The fact that you're asking questions and looking into doing it yourself shows that you're interested and you will be fine. You'll also enjoy the learning process.

Just go for it dude.

 

Haha thanks guys! I know I'm new to this and I'm pretty sure I can do it.
I just dont have a lot of engine stuff experience and wanted to make sure and see if a newbie could do it, but I've done a lot elsewhere on my jeep. (rebuilt neutral safety switch module, installed new leafs in the back etc.)

 

You will be fine if you have basic mechanical skills, which it seems that you do.

Suggestions:
Take pictures before your start so you can always go back and reference where you started from. A minute of cell phone pics can save you lots and lots of time.

Check out some stuff online, youtube has a video for everything you will be doing.

Take your time and if in doubt ask a question (do a search) before doing something that seems counter intuitive or feels wrong.

Good words:
Do one spark plug at a time, remove the wire, remove the plug, replace with new plug (check gap), replace wire. Then move to the next one. NEVER a crossed wire that way.

 

Great suggestions.

 

haha you know you are spending the money either way... getting 20 monday and 20 friday is the same as getting 40 in a week hahah

 

Is there a specific order in which to install the plugs?

 

You can install them in any order, but installing them in a row minimizes your chances of error. Make sure you mark the plug wires correctly beforehand and snap a pic with your phone so you have a frame of reference.

 

Getting back to my original post here. Got the manifold in and a new O2 in. The power I had lost is back and the jeep runs so much smoother. Cant say anything on mileage cause ive only driven it abit cause right when I fix this the power steering pump decides to start grinding loudly. Just cant keep anything fixed can you

 

My worst was 13mpg bad o2 and cracked exhaust manifold, but that was in town where I normally got 15 or so. On the HWY it was knocked down to 17 from 20 to 22. I am running bone stock.

 

Let us know the difference in MPGs you see

 

Getting back on the mileage that I'm now getting. Haven't filled up a full tank cause gas prices are so high here. Besides that it seems to get much better mileage. Still think that changing my cat out could help some but thats later down the road.
