Have any updates?? Is it fixed?

 

No not yet, family emergency came up so I'm hoping to find out tomorrow morning what it may be.

 

Ok so all of the autozones and advanced around me don't loan out their OBD2 scanners anymore so I bought the cheapest one on sale and ran the code. Ended up with the P0304 misfire on #4




So on Monday my day off I'm going to be picking up new plugs,wires,cap/rotor. Hopefully this will solve the rough idle and all around crappy running of the engine. I'm also going to pick up a oil pressure sending unit to replace the old one.
I heard Bosch products are crap on the jeeps what would you guys recommend?

 

AutoZone will read the code for free. Or you can rent one of the scanners and get your money back.

I recommend champion plugs they are OEM in all jeeps.

 

I just went out and bought the cheap scanner, I didn't want to drive it for fear of making any problem worse. I will return the scanner and get store credit and use that towards the Scan Gauge 2 which is a better all in one.

I will look into the champion plugs then, thanks for the input

 

I bought the cheap BWD oil pressure sending unit from advance auto and it works fine for me.

 

Good to know.

 

So yesterday afternoon I replaced the spark plugs and wires. Picked up Champion copper plugs, and Bosch premium wires.
Was going to install the new cap and rotor but didn't have any dielectric grease so will hopefully do that today or tomorrow.
I do have one question my rotor is pressed on instead of then two screws if I just wiggle and pull up on it, it should come off right? I don't want to break anything so that's why I'm curious.
