I've got a misfire on the #3 cyl only at idle. If the rpms are at or over 1k, it's smooth. At idle though, it shakes and the SES light flashes that there is a misfire. Code is saying #3 cyl. I havent had the chance to really dig into it yet as money is crazy tight this month. I think it may be a sticky injector or a weak coil. There is no loss in power, but gas mileage seems to be down (though I only have had the car one month and only drive 6 miles a day total so it's hard to judge on just one tank of gas) Any thoughts?
