Intermittant Misfiring
I just purchased a 2011 XKR with 8,500 miles. I've been driving it in town and it runs superbly; however, 2 weeks ago I took it out on a longer road trip and experienced the engine misfiring. I'd been driving on highway at around 80 mph (this is Texas) for a couple of hours and entered a small town requiring me to drop to 35mps and stop at traffic lights. As I accelerated from a complete stop the engine would misfire and the car would shudder. Needless to say, this was quite annoying and disturbing. Once I got back on the highway the car ran fine. I did run a bottle of fuel injector cleaner through the system once I got home. Subsequent trips back home didn't produce any repeat occurrence of the misfiring. This past weekend I took the car out of town and once again had it do the exact same thing, accelerating from a complete stop after hours of highway speeds and yet another round of misfiring and shudder. I wasn't gunning the engine just a slow steady acceleration from a complete stop. The engine light did light up for a period but then went out. Back on the highway the car ran fine. I do have a warranty and am taking the car in to have the codes read. Has anyone else experienced anything like this on their 5.0 SC engines? Any feedback would be appreciated.
