2003 rubicon 5 speed. So I had a misfire code about a month ago P0302 if I recall correctly. I switched the plugs for cylinder 2 and that didn’t fix it. I tested the coil rail with a slow mo camera and all the sparks were visible and in time with its pair. I ended up getting all new spark plugs and boom the misfire went away.
Now I’m seeing these codes and I have an intermittent loss of power and I can feel the cylinders not firing.
On a side note, I’ve recently discovered that my battery may be getting overcharged as a check gauges light came on. The battery needle would kinda fluctuate over 14 a little bit. The code that popped up when I did the 3xon off trick was p1594 but it didn’t show on my scanner.
I have cleaned the terminals and the check gauges stopped for the most part but the voltage on the cluster still fluctuates.
I’m about to really dive into the wiring and check for shorts etc, but everything is wrapped up tight and all have the plastic tubing so it will be a task and a half.
I’m wondering if maybe a loose connector maybe at the coil rail or something could cause these issues.
My plan is:
1 really inspect the wires
2 have the battery and alternator tested and replace as needed
3 recheck for spark at rail
4 replace crankshaft position sensor
5 replace cam shaft position sensor
I wonder that if I didn’t get the plug into the coil rail securely enough though because I’m missing the little red slide piece for that connection.
Any and all direction would be appreciated. I’m going to be unwrapping wires all day today so I appreciate your insights.
