Wow, That's really cheap for an Avenger.
With the late model Avengers it could be your electronic ignition module. I had problems with them. When I used to race they would get so hot they would melt the resin and short out. I don't think they liked 9,000RPM.
Before you paint yours do you mind telling us what the paint code is. It is a little code on the ID plate in the engine bay.
Like mine is AQ AQ T6, which means Aqua body, Aqua roof, Tan interior
