I got my first check engine light, though the rough idle has been an issue since I got the Jeep.
The codes were as follows:
P0122 Which is a throttle position error
P0302 Says it's misfire on cylinder #2
I put a new TPS on the Jeep Saturday, and cleaned the IAC.
The previous owner put new wires, plugs, cap, and rotor on the Jeep last week, along with a new injector on cylinder #2.
As soon as I got it I put seafoam through the gas and changed oil + filters.
I cleared the codes this evening and it started running fine, but I cleared the codes Sunday and it ran fine again until this morning. I'm not quite sure where to go from here, I'm new to the realm of the 4.0L.
Jeep is a 98 for reference.
