I have a little work cut out for me. Going to order a few gaskets, o-rings for the injectors, plugs, wires, d-cap and rotor and clean stuff up really good. That should help my mpg lol.

So today i ended up buying some new o-rings for the leaky injectors i had. I pulled them and cleaned the driver side so far. Helped the misfiring a bit. I also redid the cap and wires and made it look neat. Next on my list will be a brand new O2 Sensor, and to weld the muffler back on to the rest of the exhaust.

Sorry its been a while on the updates guys. Anyways i've been steadily working on the Jeep. I finally got a new O2 sensor installed. It doesn't run rich anymore. I've cleaned and restored the headlights for the most part they are done. I have ran into another problem though. When i was changing the O2 sensor, i must of snagged a line off of the transmission. There is just a line hanging now, and im not sure where it goes. Its a rubber vac hose with a little plastic adapter at the end. Not sure if maybe its just a breather hose that goes somewhere or not....ill snap a picture of it tomorrow. Next on my agenda will be to cut the Cat Converter off. I only have 1 upstream O2 sensor so i'm a lucky one. I'm planning on running just a straight pipe back to a nice quiet but free flowing muffler. I'm still looking into ignition upgrades and debating as we speak.
ONE MORE IMPORTANT QUESTION:
I've seen where we can do a direct swap on some better injectors with a better spray flow, do you guys know which injectors those are? Mine i think are a little gummed up and i'm making this Jeep as efficient as possible. Thanks again.

Just a warning before someone else says something.
You can't talk about cutting a cat off or anything of that nature that has to do with the cat. I personally don't even talk about cat converters.
So that being said might want to edit post to get rid of that.

Good point ok93jz. Wouldn't want the state taking anymore of "MY" money. Maybe ill just go off-roading and a rock will coincidentally rip it off. Emissions are a joke anyways.
