Yeah being blunt would work best because a lot of the things said i run to google and for a video on how to do it. Yeah it is very nice to have those at hand but bad when i have no idea how to replace parts and such and thats where you all come in hand and have already helped me alot. My old man though just says its how he learned and wont budge unless its a serious issue. To me the idle is a serious issue as to him its no bid deal but refuses to help. So again thank you

No harm in doing your own research. Taking things on face value can have its risks, another source to help verify is always good. Im glad your dad will help if it came to it, but I know you'll figure this out. And it will be rewarding..
Get under that hood with a light and trace the exhaust! When you can't trace it anymore, crawl under the thing and continue tracing. The o2 is the only thing sticking out of exhaust besides hangers! Sometimes spending a few minutes just laying under your jeep looking is a good thing. Almost therapeutic in its own way

I traced the entire exhaust and found only one o2 sensor and it was upstream. So now im on pace for that. But i turned the truck on and got under it as to listen and the sputtering is happening inside the engine and that is where i hear it through the exhaust obviously. So should i clean the throttle body and replace o2 sensor or start with one then try for the other if no progress?

I suppose no hole. I can blame that to my dad. He said there was one that and because he looked it all over i presumed he was correct. Lesson learned cant even trust my own father to tell the correct fact. what o2 sensor is most reliable and cost friendly?
Hmm. Sounds like dad owes you one.. Wait for more input but i think NGK is a good option for o2.

He sure does. I will get work on the throttle body tomorrow, most likely some more questions to come. And will get on and find a NGK o2 sensor if the cleaning doesnt help. Thank you
