So I keep getting a SES light and I have a scan tool that will let me read codes, sensor information, and even chart this stuff. I have been charting a cylinder 7 misfire, about 105 misfires every 10 second seconds. It only misfires at idle and at cruising rpm. Anything more and it doesn't misfire. Also, the #1 cylinder reads as misfiring, but doesn't throw a code. I've changed plugs and wires, moved coil packs, checked the crankshaft position sensor, tested my injectors with 12v and cleaned them out with cleaner, checked compression, and checked the ground bolt on the back of the driver side head . None of that helped. 2 nights ago, at one point in an hour drive, every single cylinder misfired at least 10 times on different occasions. I am going nuts to figure out what this issue is. It doesn't misfire at WOT at all. Anyonehave any suggestions on what to do????

 

I had a similar problem idle and cruise miss, wot fine. Coil was bad.
