Amy id? lol. You must be using an Iphone. If it only happens when it warms up, check your O2 sensors. If those check out fine, just keep it simple and stick to the basics. Air, fuel, and spark. When it's warm and misfiring, try unhooking the air inlet from the air cleaner. Check for good strong spark at the plugs; merely seeing a spark there might not be good enough. And test your fuel pressure both cold and warm.
