Hey there,

I've had my ED Xr6 for about a year and for the most part I've been very happy with it, however its always had a very intermittent misfire issue, sometimes happening when first starting up and also sometimes while driving. It will be running fine and all of a sudden it will start to run extremely rough and backfire. It will usually keep on running with slight throttle but if I let off or give it too much it will stall. In most cases I just pull over, turn the car off and back on and the issue will fix itself and I can just drive off with no issues. This has only happened a hand full of times since I've owned it but seems to be becoming a more frequent issue.

To me it seems like a possible spark issue but I'm finding it hard to diagnose since it happens so infrequently and will usually fix itself soon after it happens. Just wondering if anyone has ever had a similar issue?

Any help would be much appreciated!
