So my jeep has started having a really rough idle and the tach is for some reason like 500 off. Anyway so I have no idea exactly exactly what is wrong. There is no CEL on and I did check the bulb lol. but things I have done since it has started is replaced:

Spark plugs/wires ( twice because for some reason a couple months after change the cylinder 6 cable was shocking me when touching the outside?)
distributor cap n rotor
mobil 1 really nice oil change with bosch filter
fuel filter
and unrelated also the waterpump and blower motor

I'm thinking possibly the fuel pump? Will post video as soon as I get it back ( lent it to my cousin so that she could get to work. REGRET SO MUCH REGRET)
I just am running out of ideas... anyone have any?
Pretty much completely stumped since no CEL.

I had a rough idle and cleaned the throttle body and IAC valve and it cured it. Easy to do. There are how to's on youtube.

Oh i forgot to mention i did clean the throttle body. Not completely but ALOT where is the IAC valve?

rgr4475

Connected right next to your throttle body. Take them both off and clean very throughly with a tooth brush and throttle body cleaner.

so yours' looked like that and did it fix you're idle?

rgr4475

Yes it did after a good cleaning.. Not saying that is definitely your problem but it's a good cheap place to start.
