05 5.7L hemi with intermittent #3 cylinder misfire and intermittent trouble starting
Hello, I have 2005 jeep grand Cherokee with a 5.7 l hemi. A few days ago I had an issue where it didn't want to start. I could hear the solenoid click but it wouldn't crank. After about five tries it fired right up. This happened a couple more times that day and then it started getting a bad misfire and a flashing check engine light. It came up with a code for #3 cylinder misfire. I checked connections and ohmed out the coil with no negative results. I found a recall for the ignition switch and had that replaces. When I picked up the vehicle it started and ran fine. However this morning it once again had trouble starting and a severe misfire. Any ideas?
