Well, I just bought a 2005 LJ Rubicon. Last week I started it and it sputtered pretty good. It then threw a P300 error showing multiple cylinder misfires. I had just put gas in it and the mechanic said it could be any host of things. After running the full tank I only got 11 MPG. I ran another tank through it and it ran fine and got 16 MPG. I suspected bad gas.
I was researching a possible cause and ran across the OPDA issues with this model. Other forums are stating it's not really if it will fail but when. And when it does fail it can ruin the engine. I'm wondering if anyone locally has had or dealt with this problem.
