seems like cam sensor IS the likely culprit. everything I am reading says it will do ALL 3 of the things we had happening (roughness stalling and now no start)
I just spend 30 minutes online and my google-fu has COMPLETELY failed me. I found "TONS" of people with the same problem and same solution but not so much as a SINGLE WORD describing where the heck this stinking sensor is.
I even found pictures of the sensor but NOTHING regarding where the frak it is :-)
thank you. message sent. I will repost the images online and make a detailed post here so in the future others who search for this won't have to grind away on google trying to find it :-) paying it forward :-)
