I have a 2008 JK with a strange problem. Every week or so when I start it the check engine light comes on and the engine runs rough. After a few miles of driving, the miss goes away and it runs fine again. When the error code is checked, it shows a number 2 cylinder misfire and a number 2 fuel injector circuit open. The problem always takes place when I first start it...never during operation. I have a feeling that it is an electrial problem and not a fuel injector problem. The electrical connections are good but I have to wonder about the control circuit that drives the fuel injector. Any suggestions or similar experiences? Thanks.
