hi Michael, below are the most likely causes of this problem
1. Faulty or worn out spark plugs
2. Dirty fuel filter
3. Worn out piston rings - this is usually accompanied with smoking
4. Dirty throttle body
It can be changed depending on the system that is installed, some systems allow while others don't. Can you share the serial number/make for that radio?
