#5778, "Misfire At Idle"


Hey guys.

My car is running good and things are going well but I have this pesky misfire right around 1100-1200 rpm. It only happens at that rpm with 0% throttle. If I turn my radiator fans on or lights on to load the engine down a bit, the rpms drop to about 800-900 and the idle is fine. This is really stumping me.

The link below leads to my log file which can be viewed with megalog viewer and I also have a video to show you what I'm talking about.



I looked into it a little further last night and when it is missing, I can take #1 or 4 spark plug wires off and there is no change in the way the engine sounds or runs. There is spark in those cylinders. I wonder if it has something to do with the injector driver for those cylinders.
