Default Intermittent miss

I have a 2003 ultra with screaming eagle air filter, wild pig pipes, 203 cams, and a PCIII USB. After the bike bike warms up, 40 - 50 miles. I will get an intermittent miss while cruising and while slowly excellerating through the gears. Sometimes it will idle at 1000 rpms when stoping, sometime at 500 rpms and die if throtle is not added. When not missing, the bike runs strong. It has been dynoed at 84 hp and 95 ft.lbs. Anyone experiencing an intermittent miss and or idle problem and do you have a solution to fix the problem.

Take the PC out of the loop.....

See if the idle and miss are still there.....

If no more, well your PC Died.....

If they are still there, then it is in your bikes Engine Management System.....

Will the engine temp sensor cause these problems I am having?

Yes, it will prevent the IAC from cycling, it will also modify the spark and Fuel curve....
