Right now I am in the middle of changing my O2 senors. The drivers side sensor was a piece of cake to change. The passanger side is a different story. For those of you with stock manifolds, how did you change your passanger side? I removed the starter but still can not get a grip on it beause there is a flange right in the way. Please send me in the right direction.

 

Put on headers. I couldnt break my O2's loose with a 3ft long pipe wrench.
