voltage issues
car normally runs 13.5 volts the past couple of days it has started to drop to 10.9 to 11 with the car is at idle and once i get on the highway it will go back to 13 to 14.1. with the clutch in on the highway coasting it will drop it rmps down to 500. I'm putting my money on the battery due to the volts coming back up on the highway i wouldnt assume it would be the alternater. Any suggestions or anybody had this happen before

Fluctuating voltage that is dependent on RPMs would suggest the alternator, IMHO. Why not have it tested? Sounds like a quick trip to an auto parts store such as Advance or AutoZone is in order...
