Bought a new 2005 srt6 last month. I noticed an oil spot under the engine on more than one occasion, yep it's oil. Somewhere online I remember someone mentioned that the oil check sensor didn't seat right and that was the cause. Does this sound familiar to any of you. Also how do you access the onboard diagnostics. I just found the codes on the forum. I read the owners manual and don't remeber it mentioning the process. I need a service manual and will get one soon. And while I'm at it an intermittant air condioner problem has arisen. Any insight? Thanks!
