sp 500 backfires
Definitely sounds like a possible camshaft problem. Just had the exhaust lobe on my camshaft go out on my 1999 SP500 last month.
Acted the same way, sounded fine a idle but at about half throttle would cough & sputter and no power. I had a local mechanic do the work and we replaced the camshaft & rocker arms about $350 for the parts and he charged me $200 for the labor. I'm afraid what it would of cost going to a dealership for the fix. Hope that's not what your problem is though but sounds pretty familiar. Good luck.
